Slight tweak to note/form
Gemfile upgrade

Fog gem updated. We no longer need to point to the fog repository.
Renamed notable to memorable

We were using two terms to mean the same thing. Using the root term,
memorable.
Edit note including files

Reusing note_field partial as the edit note form. Allows editing the
linked project or contact. Also manage attached files. Placeholder
notes#new form for completeness, but it's not used.
Remove deprecated project select modal
Removed asset_host declaration

With private directories on Amazon S3 the asset_host isn't really used.
Fixed N+1 query in related_and_active_projects helper

Asking a contact for related_projects queried the database every time.
This fix simplified the helper and ended the N+1 query.
