minification of libraries was disabled for 2 reasons
- it took gulp a whole and winderful 33 seconds to run the task
- the rickshaw and ng-daterange scripts died when compressed

date-range picker has been has been fixed
min version rickshaw from site has been grabbed
we have the .min versions of scripts now, so we use gulp to concatenate them only

brings down lib.sjs file size around 40kb before zip compression
