WaspVM Focus for 0.4..

In the key of Hubert J. Farnsworth, Good news, everyone! Wes Brown has offered to fund a port of MOSREF 2.0 to WaspVM, along with some other things. WaspVM 0.4 will contain the necessary primitive functionality to support MOSREF, and some modifications to the compiler to restore cross-platform compilation. After that, I will port MOSREF back to WaspVM, and maintain MOSREF until at least the release of Wasp Lisp 1.0. Wes has a couple more contributions to the project, but we need to hammer out the details before I make more announcements.
