introducing WeWorkflow

[giovanni]

A workflow to quickly access and manage other workflows' info and folders. 

 

Derived from `alfred-extension`, an Alfred2 extension created by @jmjeong. 

Main changes: dropped `open in iTerm2`, `export`, and `disable` actions, added access to workflow info, folder, and cache, config, detection of hotkey conflicts. Workflows' info now stored in a `sqlite` database for faster access.

 

As usual, feedback welcome!
