#
#     Emote script - replace :emote_name: in your sent messages into predefined 
#   emotes (mostly but not limited to unicode). Result is visible both for you
#   and channel/query target users.
#
#     Feel free to modify or add your own ones!
#
#      (that's a lot of "emote" word, isn't it?)
#
#   commands:
#
#   - /emotes   - shows list of emotes in status window
#
#   notes:
#
#   - script doesn't work with /msg target text; must be typed in a channel
#     or query window (from version 1.10 it works with /me command too)
#
#   - Ctrl+O (ascii 15) at the beggining of your text turns off emote replacing 
#     for this text
#
#   - remeber to escape "\" characters in emotes (just type it twice -> "\\"),
#       take a look at 'shrug' emote for reference
#
#
#
#   -- CHANGES: --
#
#   - script now works with /me command (action)
#
#   - moved text output messages into nice and clean theme_register
#
