Game folder is uploaded to a server

The uploading is still "dumb", it is triggered by a hard
coded line in the beginning of the editor.py -file. Still it does
seem to work correctly, as all required files are uploaded,
including files in subfolders. NOTE that .html files should be
added to the excluded files later.

Still missing tests and comments, those must be added before this
feature can be accepted into the develop and main branches.
Editor's save-feature now uploads the game to the server

Pressing the save-button now uploads the game to the server.
There are still some bugs that need to be fixed. It looks like
saving the game once and restarting the editor breaks something,
since in that scenario the game can't be saved again.

Also added some comments to Client.py, removed some deprecated
debugging / learning-to-do-stuff functions, and cleaned up tests.py
Currently there's no tests available, and I really don't know if
I'll add any.
