Advertise install filters in ZeroMiniAVC, fix BetterSRBs name

[HebaruSan]

Problems

• The name of BetterSRBs looks weird, with a space between the R and the B
  
• Discord user dan reported frequent prompts from the dev build to reinstall mods after running the game, which said "metadata changed" even though the metadata for those mods had either never changed or changed over two years previously

Causes

• When no name is defined in the netkan of a mod hosted on GitHub, some automatic logic is applied to compute a name from the repository title, which makes some assumptions about capitalization and word boundaries that do not hold for the string BetterSRBs (it interprets Bs as a word):
  https://github.com/KSP-CKAN/CKAN/blob/228c887a0f281123ae482566479e928cc5d91886/Netkan/Transformers/GithubTransformer.cs#L200-L210
• When ZeroMiniAVC deletes files that CKAN installed, the feature from Treat mods with missing files as upgradeable/reinstallable CKAN#4067 will detect that as a mod with missing files and prompt the user to reinstall that mod, which completes the circuit of uselessness for ZeroMiniAVC since Global install filters CKAN#3458 added up-front install filters that do what it is supposed to do in a better way

Changes

• Now BetterSRBs has a hard coded name of Better SRBs
• Now the abstract of ZeroMiniAVC instructs users how to access the settings from Global install filters CKAN#3458, so users who wish to banish MiniAVC can discover the optimal way of doing that:
  
  (A subsequent pull request in the CKAN repo will improve other aspects of usability for users who encounter this ZeroMiniAVC reinstallation cycle.)

I'm going to attempt to clear the second part of this with @linuxgurugamer before merging (reached out via Discord PM and forum PM).

Would it be slightly better to filter mini-avc in the .netkans of mods that bundle it, and then make them recommend/depend on mini-avc as a separate mod?

OR somehow make an exception in the "missing files" logic for mini-avc stuff (I'm sure there are going to be other examples of mods that intentionally delete files after installation, similar to WBI though we already have a system for that).

[HebaruSan]

No, I don't think that would be better. If I did, I would have done that instead.

Heard back from @linuxgurugamer via Discord PM. He is OK with this as long as we limit the scope to note that ZeroMiniAVC may still have some usefulness for users with manually installed mods, as done in the latest commit.
