[b34] Inconsistent rounding in UI

[lukep]

I hit a snake for "36" (actually 35.16) blight damage, when it had "35" HP; it survived with 1 hp left.

I'd like to add another inconsistency. Some talents still don't round values to integers that should be integers (such as duration, range, radius, etc.). For example, the displayed duration for "Perfect Strikes" can be different depending on whether I compile ToME myself or use a pre-compiled version. The effect remained the same, though, which means the displayed duration was incorrect for one of the versions (the pre-compiled executable, iirc).

I think it would require some grunt-work to determine which talents (other than "Perfect Strikes") use non-integer integers, and I for one don't feel like volunteering to search for 'em . Plus, somebody would have to decide how to deal with 'em: floor, ceil, or use getTalentLevelRaw.
