IMSIPseudo.java: show exception error code

Current code gives E03 (AC_NOT_FULFILLED). The error codes are explained

IMSIPseudo.java: move showMsg down

IMSIPseudo.java: display menu

Add a menu with the following actions:

Selecting "Change IMSI" opens a submenu:

Change IMSI
1 Set 1 as last digit
2 Set 2 as last digit

Except for "Show LU counter", the actions are not implemented yet.

IMSIPseudo.java: change menu entry title

To make this work, flash with increased --max-menu-entry-text option for
shadysim.py. I'll add a "make flash" target for convenience.
