Now that writing xdr files is discontinued, all file operations should default to the ascii .tpa format (it's not much longer, really) and there should not be an option for saving to xdr tp format (although it should still be possible to read from that format).

Make tpa the default file format for Teapot There turned out to be one blocking technical issue for full adpotion of tpa format, and that was the fact that the printed representation of floating values inside the tpa file might not reproduce the same double when read. This change therefore introduces the "hexact" floating point format, based on the the %La format string, which produces a hex representation with exact round trips. While working on this, it was convenient to add a new representation "compact" which is basically the shorter of decimal and scientific representations, without trailing zeros. This is now the default float format, but of course one can select decimal or scientific formats to restore prior appearance. However, full-precision compact format is now the (only) format for editing cell contents, as it is accurate and efficient. Of course you can enter floating point values in any format you like when typing in a formula. The addition of several new floating point options overloaded the menus in terminal teapot, so this change also revamps those menus slightly, including eliminating the unused MenuChoice struct, and just specifying menus with an array of strings. Closes #63.
