Options are only passed to the compile command if user sets them using the
"in Compile" scope. Adjusted documentation. Options were also appended to
the lessc command after the file name, which caused lessc to ignore them.
Fixed. Also added a special "--verbose" option, which echos the command
line(s) to the console. Changed how output is generated, since lessc doesn't
want its input on stdin.
Merge pull request #6 from bmc/master

lesscOptions changes, etc.
