Masked or obfuscated entries

[Dan]

The new version will change the usage of old @m from  'memo' to 'mask'. It still accepts a string but now stores the string in a masked or obfuscated form. For example, with this entry:

@m id: myuserid; pw: mypassword

would appear in the json database (with my secret key "shakespeare") as:

"m": "{M}:w5zDjMKbwovDksOsw6XDmMOGw6TDjsOXwqPCgcObw5zCrcKQw5LDmsOiw4bDpsObw5jDmsOXw5c="

Whenever viewed in etm itself, the entry would appear in its unmasked, readable form but in the database in its masked form. This affords a tiny bit of security for passwords and such when the etm database is stored in the cloud using, e.g., dropbox or pcloud.
