* A debug version of libform will be build if DEBUG_FORMS is defined
* Can no longer edit fields that do not have O_EDIT set
* Changed background attribute to A_NORMAL like ncurses
* Fixed truncation of field contents when content length == field length
* Current field is set to first visible & active field on form post
* Bumped lib major version due to above.
* Changed debug output to go to a file instead of stderr, the file gets
opened when the form is posted iff one is not already open.
