net-im/gajim: update to 1.0.1

• convert to using distutils and update dependencies
• comment off GUPNP and AVAHI options, because corresponding dependencies are only work with python 2.x
• make NLS option default since gettext is used upon install
• SPELL option now using gspell instead of gtkspell. But, for some reason our Gspell.language_get_available() return empty list, so this feature doesn't work at the moment
• there are not PORTDOCS anymore, so remove handling of them
• actualize pkg-descr
• remove pkg-message because OTR is not ported to gajim 1.0, and CRYPTO option is self-descriptive. User can realize where plugins are stored by consulting official docs

Changelog:
https://dev.gajim.org/gajim/gajim/blob/gajim-1.0.1/ChangeLog

The main visible change is that gajim now requires Python 3.5+ and GTK3
