Issue #55: implement Go 1.5-style default usage formatting.

Compare to 1.4, the main difference in formatting is
the placement of default values. Moreover, UnquoteUsage()
is now added (and exported, for full API compatibility
with the standard flag package), so backtick words in
usage messages can be used to set the placeholder name.

Compared to the standard flag package, this patch
always prints usage in one-line, with automatic
alignment, because I feel that the 1.4 output is very
confusing when modified to include also dash-dash flags.
