Starting down the path of converting everything to 1.5 and using Retroweaver to

make things work on the client. We're starting with parameterized types which
are backwards compatible with 1.4 anyway so all Retroweaver is doing to such
classes is changing the classfile format version number. We'll get more jiggy
later as we become more comfortable with the process.
