* When a task has + and - buttons, display the buttons vertically and
expand them to fill the full height of the task.
* Use glyphicons for + and - icons
Adds a `vertical-align` property to `span.emoji` so adding an emoji to a task doesn't cause it to bounce out of alignment with the rest of the task's text.
IE11 shows checkmark in wierd position. It seems that IE does size the "checkmark" differently than firefox, which make them appear to be more to the right and bottom. I'm using glyphicons to fix that. The look is constistent in different browser. Though its kind of thicker than the original was.
Fixes#1993
* Restyle reward cost area to fit three digit rewards into default view
* Apply custom styles to rewards with higher values to prevent them
from overflowing
* Round corners for UI elements / “8-bit” outlines for RPG elements.
* Tag bar – Make it clearer that “Tags” is a heading, not an option
* Task filters – restyle in line with tag bar + nav menu
When the user has neither a plus nor a minus button on
one of their habits, the habit’s title will now span the entire
width of the task div instead of having a gap to the left.
