* API-docs now adjust depending on where 'alt' is set (either as global
parameter, or as method-parameter)
* CLI: download tracking now works for 'alt' as method-parameter
* CLI: global parameter remapping allows them to be named consistently,
but map to the name required by the google API.
Fixes#61
* set globally shared parameters (which includes 'alt')
* track if 'alt' is set to 'media' at runtime to do the right thing when
outputting the result. There is still an issue to be fixed though

It's implemented in a working fashion, except that the default value
is not currently set to something sensible, causing duplicate errors in
case the key-value syntax is wrong.

We are parsing required scalar values and handle parse-errors correctly,
to the point were we make a simple, non-upload doit() call.
It shows that we seem to build invalid calls, for now,but that's nothing
we can't fix once the time is ripe.
Next goals will be related to finalizing the argument parsing code.
Fixes#60
Now we are able to cleanly handle our arguments on a per-method basis.
The generated code won't clutter our design as we put the details into
their own methods.
Fixes#59
The hub is just using preset types - we will have to implement our own
storage and auth-delegate, as well as a Hub delegate at some point.
Dry run mode allows us to check for errors and use a call builder
using the very same code.
Fixes#57
* if there is no secret file in json format, we write a default one
that we will then read in a second iteration of the loop.
That way, the user has an example of how such a file must look like.
Next step is to cleanup the error type and implement the Error trait.
Fixes#53
