Subject: [PATCH] Mapster32: with highlighted sectors, print rot. angle; Alt +
 [,]: manual angle.

Because rotating sectors "smoothly" by 1 BUILD ang will quickly accumulate
roundoff error, this lets the user first do that as a preview and then use the
manual angle rotation do carry it out for real.
