Removal of support for queso and netcat (replaced by nmap and a SOCK_STREAM client to function as a banner grabber and as a base for enumeration tests), and a new progress bar to keep track of how far the tests have progressed.
Indivigual option checking, a fix for the start/abort issues, reenabling option locking, colorized output (easier to read the important info), a logging feature, fixes for scan options that would segmentation fault, removal of the spinbutton method for selecting scan intensity, and new nmap OS detection through UDP protocols.
