Added tests for klayout app

This commit also contains some important fixes:
 * Option -wd wasn't working
 * Relative layout file paths in session files are resolved as relative
   to the session file. On writing, absolute paths are used, so this
   change only affects session files build intentionally.

Plus:
 * Program version is available in unit tests too
 * Fixed a typo in the RBA::Expression documentation
