Linux RC Improvements

[Skyld]

I have noted down a couple of things that could make the Linux RC better.

Firstly, I've noticed that when you set a download directory for the file manager, the directory has to exist, otherwise it says `Specify a download folder in the options!'. If it could create the directory for you if it does not exist, that would be useful.
Secondly, every time the file manager is opened, the directory tree at the left hand side collapses, making it hard to continually work with one directory if you forgot that the file manager is already open. If it could reload the directory that it was in, that would also be useful.
Thirdly, in Konqueror (and possibly other file managers), clicking the RC executable opens the RC, but does not load any of the images! Instead, I had to write a shell script which cd's to the RC's directory and then run `./rc'. If it is possible to make the images load correctly from the current directory, that would be great.
