i#87893 Porting old icon fixes from AOO Bugzilla.
Removed outdated icons. Lossless compression of remaining png files.

Checked against resources deleted from ImageLists in 'dbaccess/ui/inc/browserids.hxx' circa 2004. Took a conservative approach; the following can probably be removed in future, as defined in browserids.hxx but possibly not used:
- lc014.png
- lc021.png
- lc023.png
- queryeditdesign_sc.png
- queryeditsql_sc.png
- sc014.png
- sc021.png
- sc023.png

QA - Recommend visual inspection of database icons, using different themes.
