updates

>> okay.. so it's been awhile since I've comitted anything.. some fairly significant internal changes have happened though
>> ugiFT.pas is now a complete, independent component; for now I'm just distributing the .pas file along with wiFT, but in the future I may distribute the component separately for other developers who wish to write a ui but don't want to learn how to talk to giFT. for now there is no docs on TgiFT. just read the source.
>> the creation of the TgiFT component means many internal changes to wiFT to take advantage of it. most of the external stuff should be very close to how it was before, but the code is cleaner. and will get even more clean as I keep tidying things up.
>> there's a pseudo-tree view styling to the search results window. additional sources are displayed in tree-node format. I plan to implement this styling for the downloads window as well.
there's a problem with sorting now though.. in that if you click a column and cause it to sort while something is "expanded" the children may get separated from the parents. I don't feel like fixing it just now. sometime.
oh, and there are no ImageIndex icons... this is where an icon represent the filetype will go (eventually)
>> options.ini is now configured in the source as OPTIONS_FILE. changed the default to wiFT.ini so its purpose is more obvious when wiFT is distributed along with other software (such as the giFT daemon).
>> the default window sizes are a little better now; still need to make the default column sizes better
>> can't think of anything else right now...
