feat(emacs.d): Add functions & bindings to manage global font size r/178
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
