Migrate from intltool to gettext

[yetist]

When the gettext version is 0.20 (on Archlinux), it will fail on some po files, I am not sure if this is a bug in gettext 0.20 or a bug in po file.

Archlinux build with gettext-0.20 failed at another place. https://travis-ci.org/mate-desktop/mate-themes/jobs/580040772#L1189

/usr/sbin/msgfmt: error while opening "an.1po" for reading: No such file or directory

It seems to work fine and all translation strings are in mate-themes.pot. But do you have a idea why this line in mate-themes.pot is wrong? "Content-Type: text/plain; charset=CHARSET\n" Should be "Content-Type: text/plain; charset=UTF-8\n" Issue still exits in master , so it isn't related to PR, but it is annoying because it breaks distcheckif it goes into *.po files. And we have to fix it by hand every time we send the resource file to transifex.

Installation with sudo make install doesn't install any locale. It seems that that all locale will be installed first, but later they will be removed.

Yes, it's ok, please see the $top_srcdir/Makefile.am.

# we don't want to install mo files, all translations are already stored
# in theme files
install-data-local:
$(MAKE) -C po uninstall

Opps sorry, i had forgot this special handling here in this package.

You shouldn't rename index.theme to index.desktop, all files are Desktop files in po/POTFILES.in:

diff --git a/po/Makevars b/po/Makevars
