Default values issues

[JohannesLorenz]

A list of things that has to be done on the default values branch:

• Remove the TODO-default-values file in zyn
• Finish the port checker per Static port checking #34 . Especially, add a file to the instrumentes that uses all ports (if non already exists) and add this to the port checker's description
• Move path-search to rtosc
• Don't save ports to savefile if they have rProp(alias)
• PAD synth is not saved. The reason: it depends on PADenable
• EQ.cpp's filterports are missing default values
• Scales for insefx and sysefx seem to differ => Patch Pvolume inside the effect classes
• For invalid options that are transmitted to option values, maybe check the broadcast values
• Use # for bundles, not a.
• Tests for zyn effect's presets
• rEnabled vs rExists: clarify/rename? Make a clean function?
• Fix all TODOs that arised in this branch
• Security:
  • Make buffer ovflows impossible in the pretty-scanner and the savefile reader (using safe integer structs and safe buffers)
  • Forbid blobs in savefiles
  • Pointers may only be passed in blobs (how to check this?). Reason: blobs are dangerous: parameter->subobject = *(SubObject**)message.blob_data with an invalid pointer
