[Breaking change] Rename color scheme from Forest Night to Everforest

[sainnhe]

Why?

This color scheme was created at my early stage, at that time it was basically a mixture of rhysd/vim-color-spring-night and karoliskoncevicius/sacredforest-vim, so I simply gave it the name "forest-night".

But now the situation has changed. The dark variant is not only based on spring night and sacredforest, but also based on my another color scheme gruvbox-material (inspired by morhetz/gruvbox). More importantly, I recently designed a new light variant based on solarized, which makes the name sounds strange.

Therefore, I believe it is necessary to rename this color scheme, even though people may need to update their vimrc to get it work.

Sincere apologies for the inconvenience caused.

How to update my vimrc?

Step1.

Replace forest-night and forest_night with everforest, like this:

" Old
set background=dark
let g:forest_night_enable_italic = 1
let g:forest_night_disable_italic_comment = 1
colorscheme forest-night
let g:lightline.colorscheme = 'forest_night'


" New
set background=dark
let g:everforest_enable_italic = 1
let g:everforest_disable_italic_comment = 1
colorscheme everforest
let g:lightline.colorscheme = 'everforest'

Step2.

Remove $INSTALL_PATH/doc/tags, and regenerate it via this command:

:helptags /path/to/everforest/doc/

Step3.

If you have g:forest_night_better_performance enabled, you'll also need to remove the syntax files generated by forest-night.

Typically, these files are located in $INSTALL_PATH/after/ftplugin. You can simply remove this directory, then it will be regenerated with updated code.
