PDTable Start Edit/Stop Edit button should always perform the action on click

[devel0peter]

While I was testing the installation guide I noticed that the Start Edit/Stop Edit button on a PDTable does not work in some cases.
For example, if I enter into Edit mode by triple-clicking a row, the Toolbar component should notice the fact that I'm now in edit mode and update the button accordingly.
Also, when in Edit mode, the Stop Edit button does not quit from edit mode on the first click, sometimes 3-4 clicks are required to stop editing. Clicking away or pressing ESC work fine though, so it looks like only the button is broken.
