A few little improvements to Potlatch, mostly triggered by my own experiences using it over the past couple of weeks.

First of all, when you shift-click to add a point into a way, you can now drag the point at the same time. Really useful if you're taking a rough way and making it higher resolution.

There's a "force reupload" button for those occasions when the server isn't responding and you can't get rid of those negative ids. Just press 'F'.

And, finally, you can now convert a way of unwayed segments into a way, so you needn't stop editing when you see the dreaded pink lines. Get the unwayed segments on-screen (use the options dialogue, then click the GPS tracks button). Move to a vertex on the pink line. Then press 'U'. A way will be created extending in either direction, until there's a junction, or a change in segment direction (eventually, I'd like it to automatically reorder segments, too).

I don't really like having functionality solely hidden behind a keypress and plan to make the latter two more accessible in time, but it's a start.

'Undo' next, maybe?
