Initial license copy step
Copy license file with canonical filename
Copy FONTLOG if it exists
Move TTX files to _out_src at end of ttx process
Fix license file name canonicalisation
Move directory rotation to sync_and_process() method
Fix _out rotation in sync_and_process() method

* use shutil to move and copy files
* don't ensure user folder exists, as it is implicitly created by
os.makedirs when creating the _out dir
* define paths needed
* reverse if os.path.exists(_out) to fix incorrect initial creation of
_out_old
Minor: fix indent
Minor: Change execution error message
Minor: Revert gir url in requirements.txt

* Added fonttools github repo for testing
* Changed flask-rq git url, as got this error on Mac OS X with http url:
```
