Improve query AND and OR operators of BaseCrudController

[stopyoukid]

BaseCrudController is using an AND|OR regex to split the query string. This has problems when consumers of the api are searching for something that contains the text AND or OR, such as firstName:RANDY, this will screw up the query string. We should update this to use, | and & respectively. For one they are less used in queries, but for two it is shorter and makes more sense. Something alone the lines of a regex (?<!\|)\|(?!\|) should work. If bars are used in the queries, you can escape the bar with another bar, so firstName:BOB||BOBBY.

I suggest in the meantime to implement the new way, and add a application configuration variable that tells the BaseCrudController which method to use.
