Add ability to compile sass without force
updated readme for compass force
Merge remote-tracking branch 'riveramj/master' into excessive-force
Fix word wrap in README.
Default resource:compile-sass to not force compile.

Before we had a flag to add the --force flag to the compile, but the
base version still included --force so the flag was ineffective.
Added Mike to the contributors in the README.
Merge pull request #24 from Shadowfiend/excessive-force

Excessive Force: make --force optional on compile-sass

Users can now set forceSassCompile := true to re-enable the --force flag on
compass compile when using resources:compile-sass.
