Please remove the `--` from Temp HP in the PDF export.

When printing a character sheet, places where you need to write things in, need to be blank.  For the most part, that's been done (though sometimes not with enough space).  However, the one place this has failed miserably since forever, is the Temp HP box.

It's great that when the PDF was created, they had no temp hitpoints, but the moment they gain temp hitpoints, two big horizontal bars in the middle of the cell makes it real difficult to write that in without it looking like it's crossed out.

C'mon, this shouldn't be hard to fix, so can you stop me from misprinting characters sheets repeatedly because I have to keep remembering to go back and remove the `--`.
