Update Xcode project

• Organize Vim sources
• Enable Base Internationalization
• Set "ALWAYS_SEARCH_USER_PATHS" to NO

@ichizok, is there a reason you are updating for the 2 external libraries: PSMTabBarControl and qlstephen? I think this would make updating in the future more difficult.

Incidentally, I do have some thoughts on each of these:

• PSMTabBarControl: I think we should probably leave it alone before Tabs #1120 is going to replace it. Maybe leave it alone or wait till Tabs #1120 is merged and see if we need to do anything for the new tabs project?
• qlstephen: I would actually like to remove it. It's a separate project and introduces system behavior like adding Quick Look for normal files that I'm not sure if I think should be MacVim's responsibility. Still investigating this though.

About PSMTabBarControl and qlstephen, because I only have felt their build warning is annoying.
I will revert them since it is not particularly necessary.

[ychin]

Ok thanks. MacVim has a lot of cruft like these that are using features deprecated years ago… It's a good thing to fix them up.

Speaking of qlstephen, do you have any thoughts on it (or even know what it does)? I'm still deciding on what to do with it but if you don't have any opinions on it that's fine too.

@ychin I use it to be honest to preview almost every file I have. Can you suggest an alternative if you're going to delete it?

[ychin]

@eirnym Why can't your just install qlstephen separately from MacVim? Or is it that you want to preview files that you associated with MacVim? As I said I actually haven't really looked closely into this yet to have made a decision, but I don't think MacVim should inject non-MacVim features, such as the ability to preview a file with no extensions like README. What kind of files are you trying to preview?

Also, do note that qlstephen isn't previewing the files using MacVim. It's basically a raw text preview of the file without any Vim functionality.

I'm looking into qlstephen mostly because I'm looking into #916 btw.

[eirnym]

ah, you mean files with no extensions... I usually don't look into these files. If I'd want to look into them, I could open them in MacVim by dragging them into.

I mostly do a preview for files with known extensions like markdown, asciidoc, subtitles (ssa/srt/ass), text (which is always set to default for MacVim for me), json/xml and files with code (c/c++/c#/go/rust/python. On few macOs machines I don't have Xcode at all and MacVim is mostly the only source of quick view for these files I have

With this I'd prefer the situation where a way to limit QL extension for a limited number of file types will be found leaving an ability for that in MacVim

[ychin]

Yeah ok that's mostly what I though @eirnym. Basically #126. Yeah I don't intend to break that, hence I'm still looking at what the best solution is. It may still be including qlstephen but with some modifications so it doesn't hijack the default behaviors for files with no extensions.
