pull requests: variable names

[Thomas De Schampheleire]

Hi,

In the pull request code (both controllers and templates) I find the
variable names non-intuitive and it is therefore harder to make
changes.

With this mail I would like to get an agreement on the terminology we
can change to.

- org vs other --> source/src and dest
- c.cs_repo: what does 'cs' stand for here? This could become src_repo
- c.a_repo: what does 'a' stand for here?? This could become dest_repo.

Other variable names with the same prefixes 'cs'/'a'/'org'/'other'
would be changed too, of course.

Thanks,
Thomas
