Introduce vim-clap

[liuchengxu]

#441 should be a nice option for vim and windows users.

Enable vim-clap in space-vim by adding let g:spacevim_enable_clap = 1 to your .spacevim.

There are at least two bugs about vim-clap in space-vim:

1. when I call <Leader>ff which should be Clap files, but according to https://github.com/liuchengxu/space-vim/blob/master/core/autoload/spacevim/map/manager.vim#L22, it is Clap buffers which is bound with <Leader>bb, I guess this is a typo
2. In the popup window of :Clap files, when you type a few characters in it, it will auto complete from the candidates in the list, then I found that I cannot delete characters using key like <Backspace>, check the screenshot. Don't know if you can reproduce this bug.

Just feel free to open a PR to fix it if you find anything incorrect.

I don't see your problem. Vim-clap works very well for me. If you think it's an issue of space-vim, you should provide a detailed report and minimal .spacevim in this repo. If you think it's an issue of vim-clap, then you should report to vim-clap.

OK. I'm currently using the ~/.space-vim/init.spacvim as my ~/.spacevim.

There are a lot of bindings are not usable after setting let g:spacevim_enable_clap = 1 in ~/.spacevim, and they are all related to fzf such as <Leader>pf/ps/pr/pW, I'm not sure if there are other bindings, you may fix the typo as well when you fix this up.

I restored my own ~/.spacevim to test what causes the second bug, tested it piece by piece, found that auto-complete layer causes the issue.

Then I again use ~/.space-vim/init.spacvim as my ~/.spacevim, and set let g:spacevim_enable_clap = 1 in ~/.spacevim.

And test the config files about auto-completion, and found that https://github.com/liuchengxu/space-vim/blob/master/layers/%2Bcompletion/auto-completion/packages.vim#L28 line causes the problem, but once I comment it out, there is no completion when editing in the buffer or in popup window in :Clap files, and I don't know how to fix it, maybe disable this line of code when typing inside popup window?

I have to admit that I use coc let g:spacevim_lsp_engine = 'coc' instead of auto-complete layer now, hence I don't have much time for debugging the ncm2 stuff. And also I mainly use clap at present, I may not notice the compatibility things, so the fixes will be indefinitely.
