- Extend ProxyManager::ProxyParams with crf and preset, and update ProxyTask/ProxyParamsEqual to use them. - Add global config keys ProxyWidth, ProxyHeight, ProxyCRF, ProxyPreset. - Add a Proxy Settings group to Preferences -> Disk with width/height/CRF/preset controls. - Read proxy settings from config when generating proxies from the timeline. - Add Tools -> Proxy Settings... menu entry that opens Preferences on the Disk tab. - Add ConfigDialogBase::SetCurrentTab() so PreferencesDialog can start on a specific tab.
