Added alter table widget for editing orange tables. Still TODO: for discrete variables a dropdown list of legal values should appear when editing.

Moved table styling to style.css to avoid duplication. Kepner-Tregoe widget: moved normalization (which is now optional) to the UI; moved the form elements to a nice table. Sens. analzsis widget: added nicer radio buttons.

Correcting visual appearance of configuration dialog when some items (inputs/parameters/outputs) stretched across two or more lines.

- Corrected bug: when connection is removed during the process of input to parameter conversion - it was not reflected on the UI.
- Slight restyle: visibility of drop position is enhanced and move cursor is used now.

Widget configuration access link was added to the parameter dialog window (at the bottom).
User can configure his widget by:
- manually reordering inputs, outputs and parameters
- moving inputs to parameters and vice versa
Implementation required two new fields to be added in the database Input.order and Output.order

- "Save as new" button to all admin interfaces
- admin buttons also on the top of the page
- search button on top of admin lists (always searches by name)
