Some users may have several GDAL installed, so it is usefull to show version of GDAL used by GDAL Tools plugin. Proposed patch add this info in About dialog. Also it fixes conversion GDAL version in string.

Sure, it's a great idea!

However I think we shouldn't pass the Gdal version as parameter to the doAbout dialog.
About dialog can retrieve it using the [[GdalTools]]_utils module, so we maintain the same interface for all tools.

In the attached patch there is also a cleanup converting GDAL version in string. If we want to use strings, we must use these everywhere in the Version class, otherwise the comparison may fail. e.g. ('2', 0) is not equal to ('2', '0')
