Subject: [PATCH] Improve svn2cl.xsl: Make branch selection more flexible,
 strip unmerged branches.

All included branches can be configured in one xsl:variable now, with
optional child parameters 'before' and 'after', e.g. to support
branching points and intermediary merges.  Fix the bug that the date of
a hidden previous log entry can undermine the printing of a new
date-author header for a log entry.

The branch selection based on the actual merge state:
+ csv-import
- gda-dev
- module-cleanup
