sysutils/broot: update to 1.2.1

-allow dashes instead of underscores in conf property names. This fixes a
regression as "special-paths", "ext-colors" and \ 
"search-modes" were defined
with a dash up to version 1.0.7. Now both spellings are OK - Fix #330
-fix some problems with paths containing spaces
(regression since 1.1.11) - Fix #329
