Title: Improve Form::prep_value

This provides:
* specify htmlspecialchars() 2nd parameter to escape single quotes
* specify htmlspecialchars() 3rd parameter which makes more secure output. Invalid characters will be dropped

Changes:
* current fuel converts single quote to ```'```, but this converts it to ```'```
* Invalid charactors will be dropped
