 don't think was fully baked since it only supported an either/or meek/obfs
 option. Filtering is a useful option but we should open an issue for that
 and come up with a more general solution. This is a breaking change with
 Orbot.

 > > This patch should unconditionally call `transportPluginObfs()` and
 `transportPluginMeek()` in `configurePluggableTransportsFromSettings()`
 after it checks that the file exists and is executable. We don't care if
 the transport is part of the `supportedBridges` list because they aren't
 related.

 `transportPlugin*()` methods, and that can output a single line containing
 all of the transports (`ClientTransportPlugin meek_lite,obfs3,obfs4
 exec`).
 > If we don't need to check the supported bridges, then collapsing the
 transport line is super easy. I'll make these changes.

 Great, thanks. I pushed a branch with a possible fixup commit. Feel free
 to use it or not.
