Binary data and file fields

Rdbadmin has been improved to easily allow binary data to be entered into table insert and update forms.

Each input field in the record-insert and record-edit forms now has a 'file' button (which toggles to a text button), that converts the field to a file field, permitting you to upload a file to populate that field.

The record-edit and record-insert forms are also more content-aware now, changing size to suit the field data-type; large input fields for large db fields, small for small.
