Fixed bug 5012 - KaiOS keycodes support

pelya

KaiOS is an OS for feature phones, with numeric keypad and non-touch screen, and typically 512 Mb RAM and 4 Gb flash.
It is based on Firefox OS, all apps are made with HTML5 and Javascript. SDL can be cross-compiled using emscripten and packaged as native app.
This patch adds support for star '*' and pound '#' keys on such phones to generate SDL events.
