[PD-dev] creating a flext library

I'm sure it's a good choice in most cases, but i prefer using libraries
- when they share a lot of code
- because the flext overhead is much lighter then (ok, this shall stop with
shared flext libraries)
- when there's a common info pool that is shared among the library externals
