I fixed the bug with TMR1 names.

It should be.
I just checked a TMR1 regression into CVS for the 18f family. The 18f and
16f use the same TMR peripheral (more or less). This particular regression
test verifies that TMR1 can be incremented by an external clock source.
Give me some time to verify if there is an issue with TMR1 be incremented
internally - I do know that this did used to work. But since there isn't a
regression test for it, it may be broken. (And btw, over the last several
months I've been adding regression tests everytime I fix one of these
types of bugs.)
