- gui_tools.c:new_vec didn't initialize vec->samples, causing fped to crash

- we didn't dehover before deleting, which could cause a crash
- added delete tool to canvas. Thus ...
- we no longer need the Delete key on the canvas, so we can ...
- always focus the (first) entry field, and ...
- removed "focus" parameter to edit functions
