GUI update and new options

- Moves all the tool buttons in the same place, add new options (GET
button, Report button, Subject and Password fields)
- The SPAM will now use the Name, Subject and Password even if they are
not empty. This may trigger the spam filter.
- Disable Load Proxies, GET and Report buttons while posting.
- Popup boxes "not implemented" for GET and Report tools
- The remove proxy button gets input from a popup box, not from a field.
- Fixed project property error with the icon file.
