all my work for the 3.0 version

Added countdown!

Countdown shows the time remaining before the debate or the vote ends.
Localized countdown (removed other localization files not used)

Dates in the proposal view are inside a "mybox" <div>

Added new group of words in YML files under "locale.words.*" (such as AND, OR, TOS, Privacy, FAQ)

Changed method time in class "Quorum": now it shows the time left before the debate ends;
added parameter "total_time" used to show the whole time of the quorum (needed in the history of abandoned proposals)
