Add right-click context menu

[Olympic1]

As said in #2180, here is a right click context menu. I already added a Download Contents and a Reinstall option.

The Reinstall option is just a simple uninstall -> install process. I'll work on that a bit more to show the process in the WaitTabPage and maybe a possibility to uninstall the mod whitout uninstalling its dependants.

I also added a check for the left mouse button to double clicking.

Possible implementations:

• A clean implementation of mod replacements WIP: Implement a "Replaced by" relationship #1888 - Will be implemented by @politas
• A Reinstall option [Feature] Reinstall #2154
• Select specific version of a mod to install Select which version of a mod to install #2077 - I'm having some issues with the right click menu
• A Download contents option
• A way to override the autodetected mods so CKAN can control them [Feature] Convert AD mods to CKAN control #2186
• A way to add an externally downloaded zip to the cache Allow manual downloads of mod packages #1788 - @HebaruSan can you implement this as you did in your console?
• And if we ever want to add user tagging of mods, this would be the way to manipulate those:
• • A way to mark mods [Feature] to mark mod #2176
• • A way to hide mods from all filters [Feature] Ability to hide mod from CKAN GUI. #2082
• • An Add to favourites option Add a "favourite" column. #1677
• • Set priority for mods Priority for mods #1375

Can Reinstall work for a mod that the user manually uninstalled? That's a large percentage of issue reports that come in, so it would be very helpful if we could simply say "right click ModX and choose Reinstall".

I haven't actually tested that, but I need to work on reinstall anyway. But now time to go to bed.

[politas]

This is great work, and it makes me soooo happy! if we can just exclude autodetected mods for this PR, I'd love to merge it.

[politas]

Properly handling AD mods is a whole can of worms, that I think would be better handled in a separate PR. There's a lot of different cases to consider. As this is, this throws a ModNotInstalledKraken for AD mods in ModuleInstaller.UninstallList that isn't being caught in the transaction below and thus crashes the client. Can we just make this if ( guiMod.IsInstalled )? Then I can merge this and we can all work on extending the right-click functionality one menu item at a time.

[politas]

If you could make that one change, this should be fine to merge as a solid basis for future functionality. Converting AD mods to CKAN control would be better as a plugin, I think, thus maintaining our promise that CKAN won't touch files it didn't install.

Sorry for waiting, I had to do 12h weeks. Will make the changes

Missing the dollar sign before the starting quote, I believe this will print the literal curly braces as text.

How did VS screw that up?

[HebaruSan]

Let's use CurrentInstance.CkanDir().

PR should be good to go now.
