apps/webview: make search engine configurable via app.ini, add setting to main menu (#420)

Changes:
- Added `search_engine` variable to `WebView.c`
- Modified `EventSeachWeb()` to use configurable search engine
- Added `LoadIniConfig( )` for `search_engine` in `settings.h`
- Updated `app.ini` with default **Wiby** and alternatives (**Bing**, **DuckDuckGo**)
- Added menu tab and hotkey for opening `app.ini`
