RICHED20: fix stylesheet reading and input callback

[Krzysztof Foltman]

ChangeLog:
 * Optional destinations in stylesheets are now skipped properly (and
not treated as the "proper" styles as they were before)
 * EOF condition in the middle of the stylesheet is no longer putting
the reader into infinite loop
 * Half-full input buffers don't trigger EOF anymore (although it could,
in theory, break some apps, I find it unlikely - and the change makes
Out from Boneville installer display license properly)

In case of the problems with the last change (which shouldn't happen,
but we deal with Windows apps here ;-) ), uncomment the block starting
at line 132 in reader.c
