* Fix argToUint64

* add test for change and update timestamp and version

fixes #26

the -t flag indicates a template or templatefile to use with the output.
Also major refactoring to remove race conditions and added CLI parsing tests.

By adding string as a potential source value, we then try to use it
as a filename to open.  May need to rethink the whole auto-open filenames
or we won't be able to use string values.

Also added a test to verify net/http.Get works

Refactor a bunch of stuff to make it easier to test and separate concerns
a bit better.  Fixes #11 and #6 - we have to change how we parse the
command line.  package.variable.method and package.function are ambiguous
if the package path has a period in it (which many do).  So instad we now
will separate the package path and the function/method call with a space.
Also make sure we use the package name, not the import path in the code.
