Add support for struct literal using square brackets

[micahknox]

Lucee supports the use of square brackets as opposed to curly brackets when defining a struct literal. This creates an ordered structure and preserves the order of the keys. Currently the CFLint parser sees this as incorrect synatx and flags it as an error. I propose support be added for this syntax. Here's an example of some code that produces this error:
var orderedStruct = [ keyA: 'value', keyB: 'value' ]

ACF2016 also supports this syntax.

Also, be sure to consider the empty ordered struct literals:
var orderedStruct = [:] or var orderedStruct = [=]
