Add extra arguments at (or near) the end of aapt command

[toonetown]

If you want to add additional raw file directories to the apk, you can specify them in extra arguments - however, these should come last in the aapt command (with the exception of --output-text-symbols - which is used when generating the R.txt file. This PR just moves the addExtraArguments call later in the command list.

If you add raw file directories currently does it fails?

Otherwise the code looks right. Haven't tested so if someone would like to +1 & merge that would be perfect.

[toonetown]

@Shusshu yes - if you add raw file directories and enable debug, it would fail...since the --debug-mode flag would appear after the files, and the build system tries to add a directory called "--debug".

You might want to add this to the changelog

[toonetown]

@Shusshu I can do that (add to changelog) - just the src/site/asciidoc/changelog.adoc file? Or are there different places to keep track of it?

Also - separate pull request, or should I append this one?

[Shusshu]

Separate is fine, or can you really add to this one since I merge already?

[toonetown]

Not sure - I'll just submit a new one. Thanks!
