Small but usefull enhancements to StyledText

The biggest problem with line indenting in StyledText was that only the first line was indented when word wrapping was enabled.
But right now this issue has been fixed by Felipe Heidrich.
See the snippet:
Can you see the difference between first and second paragraph? I think it will address many many issues that you had with text indentation.

The most important new API method is:

StyledText#setLineWrapIndent(int, int, int)


The patch was released into Eclipse 3.6 M4 stream, so you need to checkout SWT from HEAD to utilize this awesome functionality.
