Fixes #2538 - German umlauts for image upload
Update strings.xml

Fixed formatting (spaces). Fixed string errors, deleted extra ", fixed some bugs.

The first info was:
 "Bug fixes, improved intelligibility of some strings, the translation is more friendly now (better inflection and in czech "Tykání"). All strings should be translated now. The program was already tested with this new translation.

If any problem or question, please contact me. It is the first time I am using this kind of develop/translate service :-)"

Fix Refactoring to use Loaders fixes #2570
Fixed comment typo
Fixes #2413 - In English it is better to use "Login failed: Message from
server" since the message from server can be a whole new sentence.
Fixes #2531 - Auto-save now works as expected.

Copied saveLog(false) from onStop() also into finish(). List of caches
now gets refreshed, because saveLog() runs while VisitCacheActivity is
still running. saveLog(false) was also left in onStop(), because in
case the activity gets interrupted and finish() is not called, the log
will still be auto-saved.
