Added func-transmit (Marco's version + tweaks) which allows calling Func via a YAML interface over stdin/stdout protocol. We still need to package yaml properly as Fedora/EPEL does not have a parser that we like well enough (FIXME). We could also change this to work over XMLRPC marshalling if so desired.

+##
+## func yaml wrapper tool.
+## allows usage of func over stdin/stdin using yaml as a marshalling format
+## for access to the Overlord() API from non-Python code.
+## this should typically be accessed via a pipe, though also works as
+##     func-transmit < yamlfile
