Add the require boilerplate

Fixes a bug that sometimes comes up with load order on this module. I
know @jlee-r7 is working on a better overall solution but this should
solve for the short term.

Note, since the problem is practically machine-specific. @jlee-r7
suggested rm'ing all modules but the one under test. Doing that exposes
the bug, and I've verified this fix in that way.
New Reflection Powershell Payload

Adds Powershell payload which, unlike existing payloads does not
drop any temporary files onto the target's computer.  All needed
methods are dynamically loaded via reflection.
