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.

Rearrange and simplify text a bit, also put examples early
Most users want to see the examples as early as possible, so we place
them directly after the new (simplified) introduction. The examples
have been rewritten to separate commands from options and grouping
the command with its value, where applicable.
The rest of the document has just been auto-filled to fit to < 72
columns and sections now use === and ---- for headings to make the
README more accessible from a terminal.

This patch adds a standard configure script and converts the Makefile to
automake. This adresses PR #30, but in a more generic way, and also
eliminates the hard coded CC variable, enabling building with clang or
even a cross compiler.
Note: this is more a proof of concept and does not include the man page
generation. Another pull request addresses that.
