Add Template Toolkit 2 to recognized filetypes.
Make trailing-space highlighting slightly less obnoxious.
See if my aging eyes can handle a smaller font.
Have Vim try to colors best for a dark background.

Since I load a colorscheme within .gvimrc and not .vimrc, 'background'
is no longer set to "dark" when running in a terminal. I practically
always use a black background for my terminal windows, so this should
make Vim look a little better when I'm not running in a GUI.

Hat tip to Steven Pritchard <https://github.com/silug> for reminding me
to finally add this setting.
Remove old Control+Y keymap.

The <C-Y> keymap was a holdover from mswin.vim, and I think I'd
rather have the native functionality back.

Update to-do markers.

Add a few more common to-do markers, and remove colons from the ones
that aren't initials.
