Most CJK users use IME (input method) to type CJK characters. They need the cursor to be at the correct location, not in the bottom right corner. This CL does: * Move the cursor the focus() element. * Hide the cursor (and show it at exit) * Intercept SIGINT to guarantee proper cleanup all the time. This should fix the second issue mentionned on: https://github.com/ArthurSonzogni/FTXUI/issues/2
