Copilot and QOL update

• New terminal function inspired by the open_naviterm() function, now
  you can use <leader>tt for swithing the whole buffer for a terminal
  and going back or <leader>tw for opening a small terminal at the
  bottom.
• Now you can use copilot in this setup, which is always enabled and cmp
  is ignored until you do <leader>cd for disabling it and having cmp
  suggestions back. Also <leader>ce enables copilot again and disables
  cmp.
• Indent-blankline plugin now has small visual changes in how scopes are
  highlighted.
• Added vim-smoothie plugin for smooth use of Ctrl+D/F/U/B
• Telescope now ignores common binary files or folders to reduce
  unnecessary results and laggy behaviour.
• Treesitter works automatically now.
• Changed configurations in settings.lua for command timing, how long
  lines are wraped, how horizontal moves work and removed autoread
  because works as expected without it.
• Better comments for all files.
