wrc: Allow quotes in resource nameID.

[Artur Świgoń]

Fixes https://bugs.winehq.org/show_bug.cgi?id=786

This patch introduces two new parser states to differentiate between strings
and nameID's. An additional initial condition (id_initial) was added. Without
it, all quoted nameID's are properly recognized except for the first one.
Any number of single quotes is allowed in a double-quoted resource nameID and
vice versa.

Tested on macOS 10.12 and Fedora 25.
