No support for grid counts under 10 or over 99.

I created a grid with over 100 columns and things broke. Looking at the code, I realized that it would only work when there are 10 to 99 columns / grids defined, as there was a few calls to substr($name, 4, 2) to pull out this.

The following code uses explode('-', $name) to bypass this issue.

Sorry, the CVS server is not creating a valid patch, so I'm just pasting the code in.

The rather large style sheet & ini file segment area attached for testing, but creating a 2 or 3 grid array will also break the logic in the code.
