WIP: Suggested improvements

[mmrwoods]

• Remove --column from ag and rg opts, unnecessary
• Rename ag.vim autoload script to grep.vim
• Use smart case or ignore case with grep commands
• Increase ASYNC_STEP to 10000, better performance
• Add syntax highlighting for filetypes known to vim
• Add support for fdfind (fd binary on Debian/Ubuntu)
• Make FuzzyFiles respect .gitignore by default
• Rename g:files_respect_gitignore to g:fuzzyy_files_respect_gitignore
• Use git-grep as fallback for FuzzyGrep when no ag or rg found
• Ignore binaries when using grep, git-grep, findstr
• Rename fuzzyy_files_ignore_{file,dir} to fuzzyy_files_exclude_{file,dir}
• Change default match hl from CurSearch to Special
• Fix cursor restore in MacVim (don't change &guicursor, change hi-Cursor instead)
• Fix FuzzyCommands for commands with arguments
• Support rg for finding files when no fd installed
• Rename enable_fuzzyy_keymaps to fuzzyy_enable_mapping
• Remove default value for g:fuzzyy_buffers_exclude, unnecessary
• Add custom fuzzyy highlight groups with defaults
• Fudge smart-case for grep, git-grep, findstr
• Fix fallback to git-grep, git-ls-files after chdir
• Add g:fuzzyy_grep_exclude_{file,dir}, similar to g:fuzzyy_files_exclude_{file,dir}
• Prefer rg to ag and fd for FuzzyGrep and FuzzyFiles (much faster than ag, almost as fast as fd, one less dependency)
• Include hidden files by default, with option to disable
• Add option to follow symlinks, disabled by default
• Allow customisation of files and grep commands (ripgrep only)
• Rename :FuzzyyMRUFiles to FuzzyyMru (shorter, easier to read)
• Replace g:fuzzyy_mru_project_only with new :FuzzyyMruCwd command
• Add fewer leader mappings by default, and only those with obvious mnemonics
• Use preview window with :FuzzyHelps

TODO:

• support more custom highlighting options, results cursorline, individual popup borders etc.

Hi @Donaldttt,

First, thank you for Fuzzyy, it's a great plugin, I love the aim to have something that just works out of the box, that's exactly what I was looking for after using fzf.vim for years and leaderf for a while recently.

I think it's time I asked for your feedback on some of these suggested changes before going much further. They are mostly either minor bug fixes or changes aiming to improve the out of the box experience so it "just works" as expected for new users (as expected being obviously highly subjective). They are driven by my personal use over a couple of weeks and my thoughts on how this should work as a plugin I would recommend to relative newcomers to Vim (I have recommended it btw!).

If you have a little time could you take a look at let me know what you think. I don't expect you to agree with every change, but I hope I have explained each one adequately and you can understand why I've made it, if not, please let me know and I'll clarify.

Thanks!
