feat(emacs.d): Add functions & bindings to manage global font size

Browse source 
This makes it possible to quickly adjust the size of text in all
frames using one keyboard shortcut. Each of these functions
understands a prefix argument to mean "please only operate on the
current buffer", hence the following bindings and effects:

Global:
* `C-=`: Increase the global font size (chosen because `+` lies on the
  `=` key)
* `C--`: Decrease the global font size
* `C-x C-0`: Restore the global default font size

Local:
* `C-u C-=`: Increase the local font size
* `C-u C--`: Decrease the local font size
* `C-u C-x C-0`: Restore the local default font size
