Also made minor changes and fixes which I discovered while making
another test installation on a linux debian server.
The disk logstream now handeles files which can't be read.
Made language and theme default configurable. Also fixed minor
issues and bugs I found while testing. Looks like we can go for a first
public release now ;)
The pager button logic has been enhanced and modified
for unified support of all logstream classes. The disk logstream
supports a back and last button now. The database logstream has
be changed to work with the new logic. Minor other things have
been changed as well.
Sorting is disabled for all logstream classes now, it is simple
not implemented yet. If sorting for a field is available will be
decided by the logstream classes later.
