Christian Soffke 18dfd8f691 Reduce list title glitches when switching between menus
Each time viewportmanager_theme_enable (or _undo) is called,
the SBS title is reset, even if the theme remains enabled.
Thus switching from one menu to another, if do_menu is called
again, briefly results in an empty title before the correct
one is displayed. Even unchanged titles will unnecessarily
flash for a moment. Other theme elements that are drawn using
conditions based on the title, may also appear glitchy.

This patch adds a way to make the status bar title persist by
copying it to a static buffer. Persistent titles are not reset
by toggle_theme (although scrolling will be stopped in
viewportmanager_theme_undo), so that the theme can immediately
display the appropriate title in do_menu, simplelist_show_list,
the yesno screen, or plugins that want to keep the theme enabled.
