No more key-chord dependency, evil-matchit, tool and menu bar toggle, tweaks and fixes

• Remove key-chord dependency! It fixes a bunch of side effects with the combo key-chord+evil (fd is still working as expected but the experimental feature leader on jk is disabled for now, will be available again in the next release)
• Add package evil-matchit in spacemacs layer and enable it in html layer and auctex layer
• Add toggles for tool-bar and menu-bar on SPC t T and SPC t U respectively. See documentation
• Better fallback font for Windows: Lucida Sans Console
• Move ido split keys to C-s and C-v to mirror SPC w behavior.
• Fix SPC f f in YAML buffer (thanks to danielwuz)
• Fix error when dimishing subword-mode lighter on Emacs 24.3 (thanks to roman)
• Fix error with recent version of anzu
• Fix mode-line display error when anzu package is excluded
• Fix :nohl ex command to clear persistent highlights
• Fix potential errors when activating hs-minor-mode
• Run prog-mode hooked functions with erlang-mode-hook which drastically simplify the erlang layer
