In blockerbugs discussion tickets feedback it was mentioned that the current TRACKER VOTE command syntax is too strict and people are having troubles type it correctly every time (ticket #152 is related to this).

@adamwill said:

I would kind of like if the parsing was more permissive. I'd at least expect it to accept any combination in any order of "+1/-1", a valid vote target name, and any amount of whitespace as a valid vote.

I guess it shouldn't be a problem for us to accept all of these:

BetaBlocker +1
BetaBlocker     +1
BetaBlocker +1␠␠
  BetaBlocker +1
+1 BetaBlocker
+1    BetaBlocker
+1 BetaBlocker␠␠
  +1 BetaBlocker

(where ␠ shows a trailing whitespace)

Thoughts?
