Something should be done about recommended plugin setups

[ramojus]

We should either add a section for recommended plugin setups or add an option to mellifluous to enable custom predefined plugin setups (I have some work in progress - we could setup the plugins on LazyLoad event, which is called for every newly loaded plugin (and in the future add more events to support other plugin managers)) - that could be a nightmare to maintain though...

At least two plugins currently need this:

• fzf-lua, to set fzf_colors to true.
• dap-ui, to disable cursorline on inactive windows (setup some autocmds). Also, if laststatus == 2, perhaps there is a way to disable statusline for dap-ui windows? It looks quite cluttered with so many statuslines.
