The XDG Base Directory specification [1] demands that there should be a
"single base directory relative to which user-specific non-essential
(cached) data should be written". Light currently makes use of such a
cache directory, but hardcodes the default "$HOME/.cache".
In order to enable users to specify a custom cache directory, respect
this convention and use the "$XDG_CACHE_HOME" environment variable if it
is set. If it is not set, fall back to "$HOME/.cache".

Fix #46: Migrate to use ~/.cache/light for unpriviliged operation
When light is installed in the non-SUID root mode it cannot write to
/etc/light anymore, so we set up a ~/.cache/light instead.

Fix #45: Add --with-udev[=PATH] to configure, disables classic SUID root
This patch adds support for installing the 90-backlight.rules to gain
privileges to the kernel sysfs files. By default the classic SUID root
mode is used and the rules file is not installed.
