Subject: Added time, size and level setting types. Breaks some settings - I'll
 add automatic converter to these settings later. Meanwhile you CVS users can
 fix your config files yourself :)

Time settings allow using "days", "hours", "minutes", "seconds" and
"milliseconds" or several of their abbreviations. For example "5d 4h
5msecs".

Size settings allow using "gbytes", "mbytes", "kbytes" and "bytes" or their
abbrevations. For example "5MB".

Level settings are currently handled pretty much the way they were before.
