[FIX] Balance overview: Align summary baselines

RT­2269 #Deliver
In the Balance overview, the currency value (second column) was not on
the same baseline as the logo/currency (first column). This was due to
a different line-height for the first column.
[FIX] Interface: Enhance readability of grey text

RT­2243 #Deliver
In multiple places of the interface, #ccccca @midgray is used as text
color. This is hard to read, especially on lightgray backgrounds.
Replace color: @midgray with @darkgray where suitable, enhance navbar
and subnav hover styles.
[FIX] L10n: Merge multiple phrases into one

RT­2202 #Deliver
The phrase 'You have now connected to the gateway A for B.' appeared in
different phrases, all similar to each other. Merge these phrases to
just one, by tricking the jade extractor into reading what we want.
