repo: support avatars (#5221)

* First code for repository avatars

* Last code for repository avatars

- add new option for repo avatars location on filesystem
- add route catch in web
- add new fields to repo model
- add migration
- update settings handlers
- update repo header template

* Update locale messages

* Add repo avatars to home page

* Add repo avatars to organization right panel

* Show repo avatars in repo list

* Remove AvatarEamil field, remove Gravatar support, use generic locale messages

* Fix migration

* Fix seed and not used tool

* Revert public css changes, add them to less files

* Latest lessc (2.6.0) don't put result into file but output to stdout

So redirect output to file

* Simplify things:

- migration don't needed, and table changes too
- just upload file to repo avatar storage
- or generate random image

* Fix repo image seed - name not unique

* Get rid of not needed model fields

* Class value is enough, remove height attribute

* Don't generate random avatar for repository

- use html and semantic ui icons if no avatar found

* Update styles and templates for repo

- use repo icon as default avatar
- use globe icon for public repos
- add micro style for repo avatars at dashboard

* Remvoe redundant empty line

* Fix nl2br filter - must return string

* Fix css style for micro-repo-avatar in dashboard list

* Remove `|len`, works fine w/o it.

* Update after review 2:

- use static route for repository avatar
- format images settings block in settings

* Update after review 2:

- no random avatar for repo

* Update after review 2:

- no random avatar for repo 2
- update imports
- update UploadAvatar* functions

* Update after review 2:

- update templates

* Fix trace call

* Remove unused immport since we use static route for repo avatars.
