Widescreen hacks db: change from dbf to normal zip (also replaced the dbf with a zip of current ws hacks).

Logic stays the same as before: If no ws hack is loaded from the normal cheats_ws folder, they try finding ws hacks at the zip.

ws_cheats folder goes back to documents (following r5640, r5824 and r5826). This way the installer only installs the cheats_ws,zip file at the installation dir, while users could put their own ws cheat files at cheats_ws folder under documents. Portable mode is unaffected.

Just a couple of small fixes picked up by the compiler, no change to emulation.

Another small thing picked up by VS Analyzer. Again probably no actual change in emulation.
