Currently 'userxx' and 'orgxx' are both used as username in test files
when the user type is org, which is confusing. This PR replaces all
'userxx' with 'orgxx' when the user type is org(`user.type==1`).
Some non-trivial changes
1. Rename `user3` dir to `org3` in `tests/git-repositories-meta`
2. Change `end` in `issue reference` because 'org3' is one char shorter
than 'user3'

3. Change the search result number of `user/repo2` because
`user3/repo21` can't be searched now

4. Change the first org name getting from API because the result is
ordered by alphabet asc and now `org 17` is before `org25`


Other modifications are just find all and replace all.
Unit tests with SQLite are all passed.

This PR adds a new dropdown to select a commit or a commit range
(shift-click like github) of a Pull Request.
After selection of a commit only the changes of this commit will be shown.
When selecting a range of commits the diff of this range is shown.
This allows to review a PR commit by commit or by viewing only commit ranges.
The "Show changes since your last review" mechanism github uses is implemented, too.
When reviewing a single commit or a commit range the "Viewed" functionality is disabled.
## Screenshots

This PR adds a context parameter to a bunch of methods. Some helper
`xxxCtx()` methods got replaced with the normal name now.
