Refactoring

* move cider dependencies to top-level in project file to avoid errors
with tests and migratus
* backend support for activity feed
* partial frontend support (still needs work)
* save issue modification timestamp to db
* rename commit-id -> commit-sha everywhere for consistency
* "No data" texts for UI collections when no data exists
Changes to bounty/pull-request data model and logic
* save git sha of pull request's HEAD instead of possible merge commit
and save it for opened, merged and closed events
* only look for bounties being accepted in pull-request closed via
merge events (no need for compilicated logic with issue-closed event)
* pull_request now has issue_id column to make many sql queries
simpler

it's lack of support for modern css

generating image when a bounty is cretaed or contract balance
changes
