ppm:category filter: "ALL" should be default and combobox CATEGORY items shouldn't be hard-coded.

[s243a]

So I was slightly stumped about why on arch32pup no items showed up in the ppm when I selected the repo arch-32-core (See post). The reason turned out to be that there were no items assigned the catagory (Desktop)...at least as processed by 0setup.

Personally, I don't think that the packages should be filtered by Category unless the user deliberately decides to filter them. I personally, wouldn't expect something to be filtered by default and as a consequence I was confused by the output.

We can atually make "ALL" the default category by adding one line of code. Simply insert

<item>ALL</item>

above:
/rootfs-skeleton/usr/local/petget/pkg_chooser.sh#L544

We can do this because the function filterpkgs.sh is looking for this category:

#120813 there may be optional subcategory, put ; into pattern...
categoryPATTERN="|${fltrCATEGORY}[;|]"
[ "$fltrCATEGORY" = "ALL" ] && categoryPATTERN="|" #let everything through.

/rootfs-skeleton/usr/local/petget/filterpkgs.sh#L85
Perhaps puppy once had the option in the "package chooser" to select "ALL" as the category.

Anyway, what I suggest is that we create a variable in /var/PKGS_MANAGEMENT that lists the categories that we want to show up in the package chooser. This var could be populate via a function that reads the data from an external file like /usr/local/petget/categories.dat.

I'll do a pull/merge request for consideration.
