Use named arguments for function and allow passing additional executable
targets to be copied to the deploy tree.
Update current uses and add ipodpatcher and sansapatcher to Rockbox
Utility deployment.
This is in preparation for moving ipodpatcher / sansapatcher
functionality out of Rockbox Utility so we eventually can avoid
elevation / sudo of the whole installer. Currently this only results in
Rockbox Utility releases shipping ipodpatcher / sansapatcher
executables.
