now compiles again

Merge branch 'master' into gl

Merge branch 'master' into gl

- moved the uncolorize action to the color toolbar, renamed to uncolor

- use the keyword 'not' in place of the exclamation mark for operator!, this is clearer. also converted uses of '== false' to this.

- renamed some cmake identifiers

- now compiles with clang

- doubled buffer sizes in updaterevision to prevent GIT_HASH from being truncated

- some tweaks to version.cc

- generate gitinfo.h in the build directory, not source directory. made ldforge depend on revision_check properly

- use index-based iterating in LDDocument::closeUnused because deleting documents while iterating over g_loadedFiles causes the iterator to become invalidated

- renamed files to camelCase

- added a long int overload to StringFormatArg

- fixed various compilation issues
