added name checking to new colorramps as well

[tecoholic]

Previously color ramps when created with the same name were being replaced without warning in the style manager. This commit adds the warning dialogs.

committed your fir fix, but not second as it's unrelated to subject - plus I pushed first fix before you added second. I''l look into second

[tecoholic]

Actually I meant the second commit for @NathanW2 I wanted to make it a seperate pull request. Github just auto added when I pressed pull request, I think ;)

[NathanW2]

@etiennesky can you commit the other one for me.

[etiennesky]

@tecoholic - that's the problem with github pull requests... I found that the easiest way to separate commits in different pull requests is to have separate branches for each request.

@NathanW2 - I am adding some comments to the ticket

[etiennesky]

@tecoholic clicking on a symbol (fill style) when in the layer properties dialog crashes qgis, this doesn't happen in the style manager.

Can you fix that?

[tecoholic]

Sorry for the buggy commit. discard this thing. I have found some more GUI things that need to be fixed. I fix them and send a new request outlining the fixes.
