instead of using hard coded divisions to calculate ram stats it's better to use
macros defined in config.h. BSD port was doing this already, using macros
defined in it's common.h header. I pulled those macros out and applied them to
all platforms.
File version.h.in got renamed into config.h.in since it doesn't caontain only
the version anymore.
* Use std::sting instead of char[] in the graph drawing functions. This is the
only change to the code. Rest is just styling.
* Corrected whole code to follow Allman/GNU coding style, with 2 spaces for each
indentation step.
* Added license headers to all code files
* Added vim modelines to all files. They sit on the first line and enable the
following settings: 2 space indentation, tab expansion to spaces, line at
80th column, automatic line breaking on "\ !@*+-;:,./?" characters, automatic
line break if line exceeds 80 colums. This should keep the code nice and tidy.
