Some more bugs found

[darkone]

I'm going through whole ioFTPD code due odd crashes people have been encountering (it might be that they were due tcl script, but who knows...):

1. I had forgotten to initialise few very important pointers
2. One while () loop was shifting pointer twice, while it should have done only one shift.


I'm also making memory allocation even more efficient.

3. Memleak when using $path cookie
4. If file was deleted during upload, ioftpd crashes on upload script launch (if any)

I think that's about it Read most of the code through..

5. Deleting files within directory that does not contain .ioFTPD file causes crash
