Typos, table input height, sidenav tooltip font, project icon

Fixed typos and capitalization issues, missing periods at end of sentences, etc.
Changed the height of inputs in editable tables to match tag selector control (at its initial height, anyway).
Changed the font in the tooltips for the side nav, which inherited from the titles (small, grey, all-caps).

Also (forgot in commit comment) changed the "project" icon from the Bootstrap one (black or white only) to the Font Awesome one to make it the same color as the others.
