This changeset is a quick and dirty hack to support totp.

Hi there,

Here is a small changeset that permit to retrieve TOTP verification codes from keepassx
I presume It is not coded as it have to be for direct merge but it is a good starting point.
And regarding cmake and Qt, I'm a newbie and almost blind.

usage: set the password with the secret key and use an url like otp+scheme://user@host/
BTW, if you prefer a different trigger, otp:// (without the required + ) maybe a good choice


 - liboath is used
 - done the wrong way. (in C, a kludge in cmakelist)
