the bash scripts and makefiles for building go didn't take into account
the fact $GOROOT / $GOBIN could both be directories containing whitespaces,
and was not possible to build it in such a situation.
this commit adjusts the various makefiles/scripts to make it aware of that
possibility, and now it builds successfully when using a path with whitespaces
as well.
Fixes#115.

* add Marshal
* add BitString.RightAlign
* change to using a *time.Time (from time.Time) since that's what
the time package uses.
* return the unparsed data from Unmarshal.
