Added proper light.1 man page, remvoes help2man dependency
Update presentation of commands and options in built-in help text, as well as in the README and man page

Panic release to fix save/restore.

Various fixes and improvements. Credits to Abdullah ibn Nadjo

Add -k flag for keyboard backlight support
Cache max brightness data from automatic controller detection
Improve overall logging
Logging of clamps, saves and restores
Support for save, restore, get [max] brightness etc. for both screen and keyboard controllers

Avoid checking for write permission if just getting value
Check if controller is accessible before getting value
Avoid redondant checking
Don't truncate file contents when checking if file is writable
Fix light_controllerAccessible() and light_getBrightness() this functions were:
- Reading values from the controller
- Checking write permission even when we just want reading values
- Checking the mincap file instead of the actual controller
Don't try to read brightness values when only targetting max bright
Fix issues with string buffers and pointers
- Use NAME_MAX and PATH_MAX instead of hardcoded values
- Allow paths to be longer than 256 chars
- Check pointers everywhere
- Use strncpy()/snprintf() instead of strcpy()/sprintf()
- Validate controllers' name (-s flag + a very long name = bad things happening)
- Get rid of globals for dir iteration

First major release. Light has been around for a while now and seems to make some people happy. Also someone wanted a new release, so here you go!

Complete rewrite of program (Every single byte)
Cleaner, safer code
Completely new intuitive usage (Sorry, it was needed)
Added functionality:
- Ability to set/get minimum brightness directly from commandline
- Ability to specify the backlight controller to use directly from commandline
- Better verbosity
Probably missed some stuff
