Finally an update on the "public webpage"

After a long time, working on a separate branch I've finally decided that it is time for a merge.

Of course this is full of old and new bugs, looks a bit ugly, but some new features are also there.

New stuff:

Horizontal pin arrays: While still buggy, it now supports horizontally aligned pin arrays, and the labels can be on upper or lower side.
Refactored the JSON files containing core and module info: This is not visible, but accessing core and core packaging information can be made visible on the webpage someday using the current data file structure.
Editor Mode: For now just existing modules can be edited, in a limited way. Open a module in normal mode, then click "Editor Mode" and it can be changed.

MCU editing: During module editor testing I still had to edit the core JSON files manually. Painful thing to do, it will have its own editor.
New core/module: For now creating new stuff needs heavy manual file editing.
Edit peripherals: Add peripheral editing to both MCU and module.
And lots more, primarily for the normal usage: Peripherals need to be checked for collisions, invalid pin usage. Show visually on the module image the input/output/pwm. Include also image from backside, and have a "flip" button. Maybe include quick link to datasheets and board schematics.

And many more I forgot to mention here, plus heavy bugfixing.

For now, vacation awaits! :)
