Updates to GC/NWS, reorganisation

Added packaged versions of files to repository, update GC 0.2.2 > 0.3.0,
update NWS 0.1.0 > 0.1.1
Reorganisation for quicker build time

Moved folders so there are less clicks to build
Prevent private keys being committed
Update AP++ to v0.3.1

Fixed bug with instruments, still have to confirm sound working on all
computers
Add build scripts, update AP++ & NWS

Python one build scripts added, readme templates added, update
Autopilot++ to v0.32, update NWS GEFS to v0.1.2
Renamed folders to updated names

GitHub appears to like lowercase, and long folder names with different
hyphens and underscores are ghastly
Fix bug in build script

Build script did not escape backslashes correctly, so regex did not work
correctly - this caused great circle mode to not validate
Add GPLv3 licensing for plugins

So that users can have a definite license to follow, I've added the GPL
(version 3 or later) license so that users can use, modify and/or
reproduce this work without risk of issues or confusion later without a
license to follow.
Update AP++ to v0.3.4

Reoccurring bug involving incorrect indexes for the great circle code
solved
Start work on v0.4, move JSHint files to parent
Update Autopilot++ to v0.4

v0.4.0 brings separate autopilot controls, bug fixes, etc.
Update README.md
Place all zipped files into folder
Update README.md
Working on v0.4.1
Update Autopilot++ to v0.4.1

Fix for autopilot sound, GEFS longitude bug, and bigger input sizes.
Start work on 0.4.2

Mainly fixes to GEFS PID implementation
Start revamp of PID implementation/usage

Because the GEFS PID controller is actually incorrectly implemented,
start work on redoing it and also stop making the results dependent on
arbitrary speed ratio which makes it difficult to set limits on PID
controller.
Minor preparations/reorganisation/cleaning

Prepare for Greasemonkey support, clean up folder structure, named
folder, move binary zip files out of folder (yet to think of structure
to move .crx files), clean up unnecessary folders.
Update README to add link to Github & license

Make sure link to GNU GPLv3 and Github source code is there, to comply
with license requirements.
