Lib from illicit part 1

[iLLiCiTiT]

Description

First part of my changes in pype.lib. There are more but few functions in current lib have modifications in opened PRs and not sure if should move them?

• ffprobe_streams - https://github.com/pypeclub/pype/pull/680/files
• BuildWorkfile - Order automatic workfile build based on presets. #677

Changes

• CustomNone - removed, never used
• map_subsets_by_family is now static function of BuildWorkfile class (only place where was used)
• get_project - removed, single-line function
• get_avalon_database and set_io_database - moved to deprecated.py, they are not used in Pype 3
• ApplicationLaunchFailed, launch_application and ApplicationAction - moved to applications.py
• moved independent imports before dependent in lib.__init__.py

Question?

pype.lib contain a lot of functions which are specific for "avalon context", get_project was one of them, get_linked_assets, get_asset, get_hierarchy etc. Should we keep them in pype lib?

Those two PRs should probably be merged first, so we can keep it clean. They need some serious testing though
