Apothecary: Poco 1.5+ (REPLACES #3116)

This PR replaces #3116 and thanks to @danoli3 has been cleaned to remove most (if not all static libs).

Let's not include any static libs in this PR, but save those for a separate PR until we freeze POCO ... we're very very close!

Static libs, headers and apothecary formulas for architectures included:
- [ ] OSX FAT (32 bit w/ libstdc++ and 64 bit w/ libc++)
- [ ] iOS FAT (armv7, armv7s, arm64, i386 and x86_64 w/ libc++)
- [ ] Android - armeabi 
- [ ] Android - armeabi-v7a
- [ ] Android - x86
- [ ] Linux (32 bit)
- [ ] Linux (64 bit)
- [ ] Linux Armv6l
- [ ] Linux Armv7l
- [ ] VS 2012
