v0.2.48 : Host communication

- When used as a plugin, the host's timing (bpm and signature) is now relayed to the children plugins so they can keep in sync

- You can select a program with the host, the "plugin program" is shown in the VstAutomation tool as a pin and can be plugged to the host controller or anything else...

The "Prog" pin is the current program selected by the host

- New bridges pins : arrow shape for the direction, colors for the activity :

Bridges, a bit better now
