Merge branch 'update_interval' into 'master'

Repository update interval (#158)

This is issue #158 https://gitlab.com/fdroid/fdroidclient/issues/158

I have modified the update interval to include "weekly" and "Every 2 Weeks" and removed "Hourly" as update frequencies. THe maximum interval was daily which was still too often for me. I have removed "Hourly" as you probably have to pay for your bandwidth and that is insanely often :-). Every 4 hours should still be plenty often.

2 Languages did not have the right amount of options there anyway, and I fixed those.

Please check, test, judge and ... hopefully ... merge.
