nicolas de loof updated CONFIGURATION-284:
------------------------------------------

    Attachment: CONFIGURATION-284.patch

As discussed on mailing list 
(http://mail-archives.apache.org/mod_mbox/commons-dev/200709.mbox/%3c46F17EC2.2080600@oliver-heger.de%3e) 
This patch introduces a new EnvironmentConfiguration implementation of Configuration that uses apache Ant on java < 5 to read the platform environment. On java5 runtime it uses System.getEnv() to avoid unecessary dependency on ant.

the ant dependency has been set optionnal in the POM, as it is required only for this feature and only on java < 5

> suggestion:
> interpolation with system environment, i.e.
> ${sys:user.name} reads from systemproperties (as of today)
> ${sysenv:TEMP} reads from OS environment
> these can be parsed from a supported set of OS's - windows read from a set in a "cmd /c", unix/linux from an "env" etc. (just once on demand)
