Some tidy-up

Fixed a few bugs, tidied up some code formatted. CI testing through travis, though still very unsubstantial tests. Helcim.JS not yet functioning.

First production release (Helcim_HostedPages only)

Just the Helcim_HostedPages service in this driver. Needs a tidy, but can be used in production. Sorry, still no tests, but I do not expect the interface for the implemented code to change at this stage.
