Release version 1.1.0

Added:
- The REPL now remembers its history across program restarts.
- The -log-before and -log-after predicates, see the manpage for more
  information.
- The -class predicate to filter players based on their class.

Changed:
- Date based filters (-after and -before) will now use the filename to filter
  out logs early, speeding up the search.
- Filename output is not quoted anymore, and doesn't use double-backslashes on
  Windows.
- Ctrl-C will now only cancel the current search in the REPL instead of ending
  the program.

Fixed:
- Fixed timezone handling, so date output & filtering should now be consistent
  with the actual date.
