Version 1.5.1

Thanks to @hfloyd, the GridDataModel class now has a PropertyAlias property. If an instance of GridDataModel is parsed directly from a property value, the value of PropertyAlias will be the alias of that property (see 5226e4c).
v1.5.0 will fail during Examine indexing since it tries to use HttpContext.Current which at this point is null. Thanks to @gavinfaux and @nvisage-gf this is now fixed in this release (see 9da02ec).
