Subject: Mantis#1469. Thank you kindly, Mikem for a patch that addresses:
 Currently LSL code such as below does not compile on OpenSim, but compiles
 fine in Second Life: list mylist = []; mylist += [1, 2, 3]; mylist += "four";
 list newlist = mylist + 5.0; The problem is that the LSL_Types.list class
 does not have an operator for adding a string to a list. I am including a
 patch which implements adding a string, integer or float to a list. I am also
 including tests. The file LSL_TypesTestList.cs belongs in
 OpenSim/Tests/OpenSim/Region/ScriptEngine/Common/.
