Optimization Params Editing

And it's very inconvenient to fix the params with the modified values.
It'd be very nice if I can get the below changed:


1. Keep the edit focus in the edit control when the edit control is clicked just once.
2. Remove the -/+ tiny buttons in the editable columns. This is now only meaningful for the integer values since it only can change -/+ 1.
3. Accept the Tab key to advance the selection to the next available column field.
4. Make the 'Value' field editable so that I can apply modified value on the fly.
5. The checkbox in the left of the header label 'Name' should be working as Set or Clear All Checks.
