Fixed bug in Buckaroo parameter sorting.
Note: sorting must be case insensitive (brq_active comes before BRQ_AMOUNT) but casing in parameter names and values must be preserved.
Added an test for Buckaroo data sorting.
Use the new static sort function.
Updated Grunt file.
Improved the unit test of the array keys order.
Getting ready for version 2.7.5.
Merge branch 'release/2.7.5'
