Move textual score at the end of the animation

Instead of displaying the score as a percentage inside the metric meter
right after the computation has finished, I have moved the textual
display of the score to the end of the filling animation.

Refactor repositories layout into a partial

Since I want to display the same basic layout for the repositories page
I have moved the headline, navigation pills, etc. into a separate layout
file which is rendered as a partial.
