Remove nfc-types.h file from installed ones

[GoogleCodeExporter]

IHMO, libnfc's types should not being exposed as they are:

First, as described in Issue 147 some types are useless since we (try to) code 
using C99 standard;
Then, only one change in exposed types (even typo) broke the API;
Finally, its more clean to install only a minimal set of headers.

This file have been cleaned and all types are now used.
It can be improved, but we can consider the issue closed as there is now 
minimal set of types and newer are opaque types.
