Clean up design of the messages page

[hanford]

Hey guys, I can see myself spending a lot of time this application :p I want to make sure it looks neat too.

I did some minor UI tweaks to the messages page, thoughts?

- Remove blacked unmatch heart, in favor of the right nav Unmatch button - Add fixed Messages header, to conversation list displaying total amount of conversations - Shrink Nav icons / text to fit inside newly defined center navbar

Match count is nice!
Msg bubbles look a bit full.

Concerning the UI, I am almost done with a reworked version (few days to go). Best would be to hold back for a while, otherwise much merge conflicts.

@SaturnusDJ Should I open a new PR with just the total messages / messages header to address #7

Yeah would be nice if that got pulled, then I can see how it looks in the improved UI.
