FastBuild won't create GetTempDir()/FastBuild folder if not present

Heya!
I noticed that I sometimes had a empty monitor window, if I started the build first and then the monitor.

This is because if a build is started with FastBuild with -monitor, and the folder GetTempDir()/FastBuild doesn't exist, FastBuild won't create it, hence won't be able to write the log file the monitor reads, giving that empty window if the monitor is opened.

The folder is created by the monitor though, so if the monitor is opened first, and then the build is started, everything works :)

Closing this since it was actually a FastBuild issue that was fixed :)
