[PD-dev] [pdcontrol] reliance on Tcl

[Christof Ressi]

Cool, I'll try to setup a working prototype in the next few days.

For the gui running Tcl/Tk, the plugin concept makes sense as it's focused on that domain and not with the pd core. However for a future libpd-based app that renders patches with a different framework on a specific platform (ie. PdParty) and focused on as much feature parity as possible, I may need to suddenly support people's edge-case usage of raw Tcl without a Tcl interpreter.
