Support alternative property ordering style

[benedfit]

Closes #88

sortOrder (default: false, false | 'alphabetical' | 'grouped' | {Array})

Enforce a particular sort order when declaring properties. Throws a warning if you don't follow the order. If set to false, allow any order.

Example if 'alphabetical':

prefer this:

.some-class
    display block
    float left
    position absolute
    right 10px
    top 0

over this:

.some-class
    position absolute
    top 0
    right 10px
    display block
    float left

Example if 'grouped' (based on predefined grouped ordering):

prefer this:

.some-class
    position absolute
    top 0
    right 10px
    display block
    float left

over this:

.some-class
    display block
    float left
    position absolute
    right 10px
    top 0

Example if [ 'margin', 'padding', 'float', 'position' ]:

prefer this:

.some-class
    margin 0
    padding 0
    float left
    position absolute
    right 10px
    top 0
    display block

over this:

.some-class
    display block
    float left
    position absolute
    right 10px
    top 0
    margin 0
    padding 0

When set to 'grouped' or {Array} throws a warning if properties that are not defined in the ordering array are not after those that should be ordered.
