remove 500ms PostSelectionDelay

[jukzi]

currently org.eclipse.jface.util.OpenStrategy.TIME is set to 500ms which has the following effect: After selecting something (mouse or keeyboard) in the editor there will be a 500ms delay before the UI is update.. for example

• the link in the Outline view,
• Status Bar entry for warnings,
• highlighting the selected word,
• ...? example:

without delay all those features are almost instant:

I don't know of any benefit of the delay. Anybody does? I thought it might help to avoid too much events when let the cursor be pressed for scrolling. But those events are ignored anyway until key is released. Only if i use mouse to multiselect multiple lines there are many events, but i don't experience any lag due to it. It looks much more responsive when the outline view is updated instantaniously.

how i stumpled across that delay (i always thought the UI is just so slow that it need so much time to update): There currently is an error when you select a type and press ctrl+t within <500ms. The type hierarchy will use the statusline for progressreport but after 500ms the text is overridden by Java Editors Problem hint. (until now i never noticed the problem hint in the status bar, probably because it has that 500ms lag)
