Move LINK_ID and SCOPE_PATH regular expressions to soc/models/linkable.py.
Fix some too-long lines. Change key names back to type:scope_path/link_id
(instead of type:scope_path:link_id). Some minor __doc__ string updates.

Make editSelf() work by adding 'inheritance_line' to the list of excluded
fields in the UserForm. Also, fix a few too-long lines and add some missing
parentheses (the style guide says do not rely on operator precedence).
