New sections in the i18n developer document

[Christian Rose <menthos gnome org>]

I've added some new sections in the i18n developer document at
http://developer.gnome.org/doc/tutorials/gnome-i18n/developer.html:

What should be localized?:
http://developer.gnome.org/doc/tutorials/gnome-i18n/developer.html#what-localize

Avoid creating multidomain modules:
http://developer.gnome.org/doc/tutorials/gnome-i18n/developer.html#multidomain

Empty strings:
http://developer.gnome.org/doc/tutorials/gnome-i18n/developer.html#empty-strings

Translator credits:
http://developer.gnome.org/doc/tutorials/gnome-i18n/developer.html#credits


I'm not a professional docs writer and I'm confident it shows. However,
I wanted to have done something to prevent some topics from having to be
repeated over and over again on mailing lists, and some mistakes from
appearing again in modules. ;-)
