[lazarus] New Tests of the IDE

[Jens Arm]

Hi
I have found some not correct working things:

	Search/Replace couldn't be started
	It isn't possible to search case insensitive (the checkbox
	don't work)
	Editor options/Display/Extra line spacing & editor font
	height isn't saved
	In the editor options (Display or Color) if I try to scroll the
	editor then nothing works anymore (no Mouseclick on Buttons).I
	think that it is a very important thing to get the scroller working,
	because it is very bad if nothing works after using the scrollers.
