Go to line vs show selection

[jlaurens]

Sorry if it is outdated, I can only use version 0.6.5

Bug description:

When opening the go to line panel, the line number is automatically set to the one of the actual selection.
That is not really helpful because we can go to the actual selection using the show selection menu item, which is far more practical. It would be more interesting if the go to line panel could keep around the last line number entered.
