miRack Eurorack-style Modular Synth

miRack is a Eurorack-style modular synthesizer for iOS

In the meanwhile, this is a minor update with the following changes:

* Multicoloured cables!

* Added an item to the tools ("wrench") menu that zooms the rack to fit exactly 2 (3 in portrait orientation) rows of modules.

* New modules: 8Mode softSN Machine - a very interesting emulator of TI SN76477 "Complex Sound Generator" sound chip from 1978; trowaSoft MultiScope module; "ML Modules" pack.

* Fixed a crash when adding SquinkyLabs Mixer8 module.

* Removed two Bogaudio spectrum analyser modules for now. They will be back once we're completely happy with their performance on iOS devices.

* Some of the graphics and also Befaco and ESeries module panels have been replaced to avoid possible licensing issues.
