Add support for arter97's chromium build, Remove useless tugabrowser.beta

[bladehawkz]

Tugabrowser's builds all now have the same package name of "tugapower.codeaurora.browser", so we can now remove the old name

Thanks, hadn't heard of this one. This shouldn't be required anymore with this commit: ddd3dcc but I'll merge anyway 👍
