Submodule support

[Louspirit]

Adding support to do all git operations for GIT Submodules that would be located in the Plugins folder.
The use case is sharable content plugins you would maintain outside the project repository.

See SRombauts/UEGitPlugin#44

Thanks for this! Looks feasible on first glance, will review it hopefully later in this week!

I fixed a compilation error. Made a push force using a rebase interactive to keep one commit.
It should be ready to merge now.

Hi, I've been getting really behind D: I'm really trying to catch up on my Unreal Engine work but I will have reduced time until maybe May or June

Hello, just coming for news 😁

Just rebased your changes to latest locally, it works on sub-modules, and blueprint diif.
(though I didn't think I changed any of these "PropertyAccess" things, it should be the mistake of blueprint diff tool)

As suggested by @ameaninglessname, I did a rebase with the latest stuff, removing conflicts. You can do the merge when you're ready @mastercoms
