BP-167-Extra-Blocks-in-Editor

[gummyfrog]

Changes

Editor overhaul. List of changes:

1. Styling. Editor looks closer to the home page.
2. Error catching. Invalid workspaces are not saved. A workspace may be invalid for any of these reasons, checked in roughly this order:
   a. Missing Metadata Block
   b. Missing Metadata Fields
   c. Missing Game Loop Block
   d. Missing Exit Game Block
   e. Workspace does not compile
   f. Game does not run

Game running may not be something we end up checking at file save time. This can error-caught when running it from the home page if the background pygame run ends up being intrusive on the Pi. (Preliminary tests show that it is not.)

3. Game icon saving.
4. Overhaul the Python generator. No pygamezero.
5. Overhaul available blocks. Should be much simpler now, reduced time to moving guy by quite a lot.
6. Explicit working directories for the flask server, compiler, and compiled games. These should be safe to run from any directory now.
7. Endpoints in Flask for running and compiling a game, either in test mode or actual run mode.
8. Changed keypress handling

Tested & Verified

1. Editor access from external machine
2. Editor error catching, both on the blastpad and from external machine
3. Running a game via endpoint
4. Testing a game via endpoint
5. App starts from start_x.sh
6. Game runs from editor
7. Game saves from editor
