[crossfire] CVS -> SVN conversion

[Mark Wedel]

  Just a note/reminder of this change:

  Crossfire will switch from CVS to SVN this onday, Sept 18.

What will happen:
- Current CVS repository will remain available for read-only access, but no 
future changes will be made to that repository.  The CVS repository will purely 
be for historical reasons (want to see what 1.6 looked like, etc.)  Developer 
permissions will be updated to remove CVS write permissions.  The crossfire page 
on sourceforge will also be updated so that CVS info will not appear.

- The SVN repository will only import the head trunk, and not the tags or 
branches of the CVS repository.  Future tags and branches will be made of course.

- Only actively developed portions from CVS will be moved over.

- Instead of having a copy of the editor in crossfire, we will link to the 
Gridarta project.

- Some amount of cleanup in the repositories will be done - mainly, this means 
that some automatically generated files will not be included (flex files, 
collected archetypes/images/etc).  The autoconf/automake files will stay in the 
repository, as it is general practice that code can be downloaded and then a 
simple configure run.

- The server portion will be renamed from 'crossfire' to 'server' to more 
accurately describe what portion it is.

- The organization will be server/trunk, client/trunk, client/branches, etc.

After the fact:

- The server and client will need some updating to get the version number so 
they can print that out as a build revision (instead of showing revision of each 
file).

- Branches for 1.x will be made for the different components.

- Likely some other cleanup will be necessary.
