Release 0.7.1

Fix a crash when navigating the Messages menu with voice prompts enabled:
menu strings added after the voice-prompt pack was built read past the end
of the table of contents and now play silence instead.

Bump version to 0.7.1.

+- **Fix:** the radio **crashed** when navigating the Messages menu with voice
+  prompts enabled. Menu strings added after the voice-prompt pack was built map
+  to a table-of-contents slot that doesn't exist; the player read past the end
+  of the table. Such strings now play silence instead (also hardens the
+  pre-existing strings sitting at the end of the table).
