Temporarily remove travis branch restriction

untagged-fe679610ade0c039019e: Never show warning dialog box in command-line pkg installs.

Also,
 - add Background Music Device.driver to the array of bundles in
   pkgbuild.plist, and
 - don't warn about the permissions of the install dir for BGMXPCHelper
   in build_and_install.sh if it's only building.

untagged-6ace52643e9e3fa9daa4: Try to fix Travis not finding the files to release.

Also, make sure commands in uninstall.sh use the binaries that ship with
OS X and add the release files to .gitignore.
