spec: mention more EF to invalidate

IMSIPseudo.java: Cosmetic: fix missing space

Invalidate Kc, too

Invalidate TMSI, P-TMSI after changing IMSI

Now the ME doesn't try to send the TMSI anymore in the next Location
Updating Request, it directly sends the IMSI.

add SIM REFRESH command after IMSI change

Test: Bytes.toStr()

refactor the menu, the mi2str() implementation, and tests

Instead of a sub-menu for changing the IMSI, just offer a dialog with the
current IMSI pre-filled in an edit field.
"Show IMSI" becomes just "Change IMSI" without changing anything.

Change mi2str() so that it simply returns a byte[] of the right size....

make writeIMSI() safe against invalid length

drop unnecessary 'new byte[]' before {...}

prompt(): add prefillVal arg
