minor cleanup of slavePortnum config
adjust tests for cleanup
rename startCommands to remoteStartCommand
Merge branch 'p/rename-startCommands' of git://github.com/djmitche/buildbot into slave-proto
Extend EC2LatentBuildSlave to support spot instances.
Added MultipleFileUpload step.

Use this to upload multiple files at once. Supports all the options of
FileUpload and DirectoryUpload. Makes use of the "stat" command to
determine the kind of file that is uploaded. "Skips" if slavesrcs is an
empty list. "slavesrcs", "masterdest" and "url" are renderable.

    transfer.MultipleFileUpload(slavesrcs=['some/file', 'some/directory'],
                                masterdest='targetdir')
Refactored FileUpload test
Type (timestamp -> srctimestamp)
