Update crypto summary and lvl2 icon
* src/dialogs.rc: Use the same icon for lvl2 and 3 * src/mail.cpp (Mail::get_crypto_summary): Change wording. (Mail::get_crypto_summary): Fix comment. (Mail::get_crypto_one_line): New. Move one liner also into mail class. (Mail::get_crypto_details): Minor wording change. * src/mail.h: Update accordingly. * src/ribbon-callbacks.cpp (get_sig_ttip): Use one liner funct.
The difference between trusted / certified highly trusted
is more confusing then just using "Level" imo. Different
security levels are a real world concept and are hopefully
understandable.
