Add repository url

[joacar]

Fix #109

Added

• Get repository url from remote. Default is 'origin'. Can be configured via GitRemoteOrigin GitRemote

Proposal

• Write full url "$(GitRepositoryUrl)/tree/$(Commit)" (default) that the assembly was built from

Task

• Change GitRemoteOrigin to GitRemote
• Default for GitRepositoryUrl? "http://localhost"
• Handle failure getting url
• Rebase before merge
• Merge style (squash, rebase-fastforward, ..)
• Add default remote name Set default origin early

Is there any way I can force generation of the static language files to check that they compile?

[joacar]

In CI build I can see that the value for the executed task to retrieve repository url is https://github.com/kzu/GitInfo.git. On my machine there is no trailing .git and I haven't seen it in other projects where I used this. Should we check if it's present and remove if so?
Perhaps not worth to bother with since it redirects to correct address. Could be potential issue with crawling and not following redirects.

Adding the .git suffix is optional when cloning the repository. I think it's fine.

This looks great, thanks a lot!
