Changes to move documentation to Info capability

[DSMasterson]

README.md: deleted
README.org: revamped docs
Makefile: rules for making docs
org-vcard.info: generated Info file (needed for MELPA)
dir: generated directory addition so Info can find org-vcard.info

Note: after adding this change, you'll need to update MELPA to pickup the org-vcard.info and dir file. You can also drop sending the README file to MELPA -- the info file will be the documentation. However, README.org will be used directly by Github like README.md was.

Hi! Thank you for the PR! I think moving to Org for the readme is a good idea, and had been planning on doing so at some point. Furthermore, while I like the idea of org-vcard documentation being available via Info, I don't like the idea of putting "compilation output" under version control, so I'm of two minds concerning the automatically generated info files

[DSMasterson]

I understand your concern about "compilation output". Normally, I wouldn't do that, but IIRC, MELPA doesn't have the tools for doing the compilation -- it will just pickup the specified files from a designated repo. Therefore, we're stuck.
