Merge lp:~mterry/indicator-power/snap-root into lp:indicator-power

[Michael Terry]

Work inside a snap by prefixing hard coded paths with $SNAP.

There are also two hardcoded paths in the data/*.desktop.in files. But that's a static desktop file, so $SNAP isn't appropriate.

I'm not sure what the best solution for those is, but presumably it would lie in whichever component consumes the desktop file, not this package.
