Diff to Config/IniFile to allow datatypes to be stored

I have written a patch to Config/Config/Container/IniFile.php to allow storing of datatypes along with key/pair values. This doesnt break backwards compatability. Adding a similar functionality to the other storage types shouldnt be too much of a problem, although I havent looked into it too deeply. The reason I am doing this is I want an easy to configure frontend for either web or gtk applications. To do this, you really need to know what type of data it is (partly for choice of widget/partly for data validation). At the moment I have just used the markers bool, string and numeric, but this could easily be expanded to include multiple fixed results (such as Male/Female of if defining a database type) How do you guys feel about expanding this functionality to the other containers, I should be able to do most of the work... I just need the relevant number of +1's (how many do I need for this kind of thing? ;) Mike
