configure: Correct the USE_NLS check properly.

Apologies for failing to ensure it is disabled properly when requested.
Add a few checks to groupserv/flags. Restrict +f from +Fing themselves. Prevent +f-F from removing founders. Prevent removing the last founder of a group. Make sure +Fs always have +f.
configure: Avoid non-standard == in test(1).
Warn opers every 10 failed login attempts, instead of only on the 10th attempt.
(too long for short summary)

Updated 2011->2013;
imho, having to update that text every year is annoying; for 2012, it was entirely forgotten. What about something like "2005-present"? :D
help/default/cservice/flags: Clarify flag interop.
gitignore: Ignore src/ecdsakeygen/ecdsakeygen.
gitignore: Also ignore ecdsadecode & ecdsasign.
