Add ability to mimic highlight link behaviour in g:jellybeans_overrides

[oryband]

I wanted to do highlight link Folded Comment with jellybeans, but was first to actually do this instead, because there isn't such option:

let g:jellybeans_overrides = {
    \ 'Folded': {  " Copied settings from :highlight
        \ 'ctermfg': '244',
        \ 'gui': 'italic',
        \ 'guifg': '888888',
    \ }
\ }

Can this be added somehow?

s/first/forced/ I think. :-D

I'll add a "me too" as well as an additional use case. This is useful not just for built-in values, but especially for plugins which add their own custom highlight definitions (e.g. vimwiki adds VimwikiHeader1-6). I'd like to be able to do something like the following, which would allow having the definitions separated in a single location.

let g:jellybeans_overrides = {
    \ 'VimwikiHeader1': {
        \ 'link': 'ConstantBold',
    \ }
\ }
