When the Linux console is e.g. switched to a graphical VT, the kernel emits \x01P to notify that it is not able to read the screen any more, and the software synthesis can thus release the audio card, for other screen readers to take over. This implements it by adding a paused_espeak variable that tracks whether we have suspended espeak. When more text comes, we can simply reinitialize espeak. This fixes #10.
