Paul Gilbert e44c5bdcc6 TITANIC: Introduce movement via arrow keys
This also fixes a bug with Page Up, Down, Home, & End not working for
the Conversation tab. Additionally, code for scrolling individual
lines in the conversation and glyphs via the arrow keys has been
removed in favor of this centrallised movement, since they were
somewhat redundant, and the mouse wheel can be used for scrolling.
