Reworked exports and filtering

 * Exports now generated by sending the list of ids to export
 * Allows arbitrary JS filtering without having to do the same on the server
 * Had to branch slick grid to deprivatize some of DataView's internals

+Version: 1.6.0 - 2017-02-23
+    * New (customized) version of SlickGrid (branched from 6pac@github)
+      * allow access to the default filter and the filtered items
+    * Handle exports by sending a list of ids to export rather than
+      trying to recreate the full filter set serverside. Allows rather

+Version: 1.5.6 - 2017-02-22
+    * allow easy button column width configuration

 Version: 1.5.5 - 2016-12-16
