Problem: whitespace style too restrictive.

[kurdybacha]

For header only library like cppzmq, whitespace style inherited from
libzmq is too restrictive.

Solution: relaxing whitespace before parens from always to in control
statements only, increased max column width from 80 to 85 and removing
requirement of whitespace after template keyword.
