Move the input box to a GtkSourceView

We already depend on GtkSourceView for spell checking and this will allow us
to implement completions for nicks and commands and other stuff we haven't
thought of yet.

I'm not super happy about tracking the adwait style manager, but that seems to be the only way to make sure the style matches the rest of the application.

Testing Done:
Compiled and sent some messages.

# UPDATING VERSION NUMBERS FOR RELEASES
#
# The version number is:
#   <major>.<minor>.<micro><extra>
#
# micro += 1
#
# If any functions have been added to libpurple or Pidgin:
#   micro = 0
#   minor += 1
#
# If backwards compatibility has been broken in libpurple or Pidgin:
#   micro = 0
#   minor = 0
#   major += 1
#   purple_soversion += 1
#
# extra should be similar to one of the following:
#   For beta releases:          '-beta2'
#   For code under development: '-devel'
#   For production releases:    ''
