gEDA-dev: libgeda library version & stable branch

[Ales Hvezda]

I better clarify something:

[snip]
>	* Stable releases will be called 1.0-RELEASEDATE.

	"major number"."even number"."minor number"-RELEASEDATE

	Example: 1.0.0-20070601 1.2.0-20070605

[snip]
>	* Unstable releases will be called 1.1-RELEASEDATE.
>

	"major number"."odd number"."minor number"-RELEASEDATE

	Example: 1.1.0-20070602 1.3.0-20070607

	Same sort of scheme as other free software projects out there.
