fix a crash from chroot of invalid keys, and make keybindings reload better

since invalid(not translated) keybindings are allowed in the tree, the tree's structure may actually need to change when reconfiguring.  actually, it could need to anyways.  so when re-translating all the keybindings, actually rebuild the keybinding tree.  also, make the chroot building code not fail when translate fails, to match the rest of the code and avoid segfaults with chroots on invalid keys.
