On keyboard interrupt in the regular flow of downloading the collected images of this session and of last session are saved so as not to destroy the archive accidentally this way.
If an item is added to the new collection, it is removed from the old one.
If a save is being dumped (uncleanly saved because of KB interrupt), the old collection is appended to the new one.
Upon loading the returned string is split to enable removing of the old items.
Using kirbybase to store downloaded images
A nasty bug that always returned the wrong result when checking whether an image had already been downloaded has been fixed
After a file has been downloaded a callback function can now be called.
The callback function I call checks to see if the resolution of the image appears in the collection of resolutions that has been entered in the configuration file and deletes/moves accordingly.
If a file can not be read (which I have noticed happens sometimes), it is removed, not copied and not archived so that it can be retried later.
4grab got a new command-line option, -s --sorter, to sort out old images, running python sorter.py has the same effect, but this seemed pretties.
theoretically multiple categories could now be entered into the configuration file seperated by ',', but this hasn't been tested yet.
mutliple resolutions could be entered into the configuration file, seperated by ',' like so: 1680x1050,1920x1200.
Configuration now checks to see if all the necessary properties are available in the configuration file, if one is missing, it tries to create it.
config now has an optioncreator property that will allow another module to select how to prompt for a property
resolutions and archive options have been added to config file for sorting functionality
download.py no longer requires progressbar.py, it now contains a class that accepts another class as a parameter, this may be useful later when adding different ways of interaction
With --thread a signle thread ID or thread URL can be entered.
If thread is a URL, it will download it.
If thread is an ID, a category must also be set.
Configuration Settings can now be changed with the -e command line argument
execution of 4grab has been moved to 4grab.py, but should also still work with download.py
Windows was giving trouble with the os.getenv(HOME) which can be executed in the python shell and IDLE and will return C:\Documents and Settings\username\, but when running a script it will return None.
If os.getenv(HOME) is None, then now the exec dir will be used instead
* Seperated the parser from the downloader code.
* Added a progressbar class, to make it look fancier
* Created some functions to do all the work in downloader.py, cleaner now
* Changed parser.py to htmlparser.py, since it was conflicting with a built-in module
