[TASK] Remove non-lib folders from the lib folder

[james2doyle]

lib/cache
lib/datastorage

Where would be a better home for these? I want to keep the top level folder clean, so finding a decent place for these would be nice. Maybe something like storage/{cache,datastorage}

as described in #133 this folders should be part of the core. maybe auto create on first run

[NeoBlack]

here is a first implementation: https://github.com/NeoBlack/Phile/tree/feature_1_4/createFolders

new folder structure:

protected/cache/
protected/datastorage/

these folders will be created from bootstrap class. There must be implemented some more checks and error handling, but it shows my idea.
