Add image quality handling to QTextImageFormat

This patch enhances QTextImageFormat with a property for image quality.
Default will be quality of 100. The user may set different values with
setQuality(int). QTextODFexport will export images as png if quality is
set to 100 and as jpg with the compression quality set to the given value
if smaller than 100.

[ChangeLog][QtGui][QTextImageFormat] Adds two new functions to the class:
setQuality(int=100) and quality(). Is currently used by QTextODFWriter to
determine the image type and quality when exporting images to ODT files.
