no more stalling while waiting for a disco info while sending a message.

We need to check if the remote entity supports 0184, but if it doesn’t
support disco#info, then we will get an iq type="error" and nothing
will be cached, leading to disco#info queries being sent each time.

Keep a cache valid 2 hours of the JIDs which replied with an error.
TODO: check that this the kind of time period we want.

- two options request/ack_message_receipts
- two new theme parameters : CHAR_ACK_RECEIVED and COLOR_CHAR_ACK
- if a message has a receipt, the character is displayed between the
  timestamp and the nick, using the color

also bump version, and add some gettext wraps

- fallback to mediated invitations if only the bare jid is given to the
  command or if the jid does not advertise support

TODO: provide a way to send passwords

fixes whitespace issues, some builtin overrides, and some enormous lines

might make poezio run nanoseconds faster!

(thanks eijebong)

config.get('option', 'value').lower() == 'value' is just ugly and
stupid, especially for bool.

One if in basetabs:556 was also missing a comparison, leading to True
whenever the option was set.

And put reasonable defaults

Add a force_encryption option set to true by default.

Thanks to Florob for the initial input

We can now change the keepalive values with /set, without restarting

add two new options:
connection_timeout_delay and connection_check_interval

- Add an option enable_carbons (defaults to false)
- Make a disco on non-roster entites to determine if the message
  commes from a muc private chat or not.

Also fix the copy of the default config if -f is used

- configuration options
- theming options
- /gaming

- Added as always new theming variables:
    CHAR_ROSTER_MOOD, CHAR_ROSTER_ACTIVITY (a SNOWMAN!)
    COLOR_ROSTER_MOOD, COLOR_ROSTER_ACTIVITY
- Added two new notification types in Theme.INFO_COLORS (mood/activity)
- Added new configuration options:
    display_mood/activity/tune_notifications (those can be set for a
    specific JID)
    enable_user_tune/nick/activity/mood
- Added /activity and /mood commands, with completions
- Moved the old /activity to /last_activity
- Details are show in the ContactInfoWin if there is room, or with "i"
  on a contact in the roster.

- add a use_pep_nick boolean option
- use it as a nickname for roster contacts, but it does not
    supercede the user-defined handle
- send a <nick/> at the beginning of a normal chat
- not implemented in MUC (wontfix)

- Add new theming options
- Show the tune in the roster (both in contact line and infowin)
- add an option to show tunes as info messages

- remove the help message for people still using the old custom
    sleekxmpp repo

- remove the decline command that is not in the trunk (and mediated
  declines are supported nowhere anyway)
- change a bit xhtml-im support
- change the bookmarks management a bit
- Add a verification to avoid crashing when poezio will be launched the
  next time
- Fix the (unrelated) bug when setting a jid affiliation

This is now already done in sleekxmpp, so I added a “lang” configuration
option. TODO: use the locale of the system.

(notably, the /message one)
All JID calls in poezio’s code were already covered, but sleekxmpp does
that, too, so each jid given to sleek must be validated, otherwise an
unwanted exception may occur.

- Add a /activity command
- Load xep_0012 on start
- Add a 'l' shortcut in the roster to get the last activity
- Using "/activity" in a direct conversation will add a message in the
  conversation, and not in the info buffer.

- Add /block, /unblock, and /list_blocks commands
- Enable the commands only if the server advertises the feature
- http://xmpp.org/extensions/xep-0191.html#example-9 was not tested, but
  should work (could not find a server to test with)
- Add documentation for the commands

This is in prevision of a sleekxmpp update with JID validation.
Also, comment the “server” option in the config file a bit better.

- with reattempt = True & max_attempts = 0
