Bump version to 1.19

- Put CMakeLists.txt in the source zip, not the old project files.

SVN r2633 (trunk)

- Bumped ZDBSP version to 1.16.

- Fixed: ZDBSP stored seg vertices in 16-bit words, so it failed to write proper nodes for
  maps that ended up with more than 65536 vertices after node building, even though it can
  write formats that could support it.
- Sync debugging output between ZDBSP and ZDoom's internal node builder.

SVN r2388 (trunk)

- And since I just made a fix for ZDBSP, I need to merge it into the …

…tagged 1.14, too.

SVN r2133 (1.14)

- Version bump ZDBSP and add x64 configuration to the VC2005 project.

SVN r1495 (trunk)

- Make sure people know this ZDBSP isn't from 2006.

SVN r1340 (trunk)

For ZDBSP:

- Fixed the OrgSectorMap generation in FLevel::RemoveExtraSectors().
- Added a version of ClassifyLine compiled with SSE (but not SSE2) optimization
  for people with Pentium 3/Athlon XPs to use.
- Added ClassifyLine backpatching for the GCC Windows build. The first time a
  function calls ClassifyLine, it has to check which version to use and jump
  to the appropriate one. After that, it calls the desired one straight away.

SVN r227 (trunk)

I thought I already added these.

SVN r177 (trunk)

- Added support for creating v5 GL nodes to ZDBSP.

SVN r159 (trunk)
