Pedalgrid

Added pedals and stompboxes to the supported ModularGrid formats. The planner is very basic but may work good enough.
There are nearly 500 pedals already, I hope it will grow.

Advanced Pedal Uploader

The pedal uploader is capable to cut white background out of JPGs and convert them to transparent PNGs.

Support for transparent PNGs

Transparency of modules and pedals is preserved after upload.

Cleaned up CSS

Cleaned up the CSS files which were cluttered with hacks to make old browsers work. No support anymore for legacy browsers, it's not worth it.
