Add layer import script

Browse Source 
Adds a simple way to add a new layer to the database in an automated
manner, given only a URL and optionally a name and subdirectory. If no
subdirectory is given, the root and all first-level subdirectories that
contain conf/layer.conf will be created as layers. Guesses will be made
as to the right values for certain fields, by looking at
README/MAINTAINERS files and github repository information.
