Final release as standalone script (no root needed)

From v1 onwards indicator-keyboard-led will be packaged into a .deb archive.

Some resource locations will be hardcoded (e.g. locales, icon) to /usr/share/wherever.

The above also implies that root privileges will be required to install this indicator.

v0.99 marks the final version which runs on its own without needing root (assuming dependencies are met).
