Update Vim plugin YouCompleteMe.
Update YouCompleteMe for the third time in one evening.
Add Vim plugin Tagbar.
Add Matlab to spell dictionary.
Switch to search files in CtrlP.

Previously I used mixed search but it shows too much irrelevant files.
Remove setting of g:ycm_path_to_python_interpreter

Previously the system python 2 was used for YouCompleteMe plugin.
However, now special python 2 is used so setting of this option
is not needed anymore.
Add setting of g:ycm_autoclose_preview_window_after_insertion
Add Vim plugin Gruvbox.
Remove autocomplete option for preview window.

During autocompletion the preview window appears which is very annoying.
Return to using Powerline symbols in airline and tmuxline plugins.
Add smart detection of case-sensitivity during search in Vim.
