* Fixes#11856
* Set the minimum recommended wordlist size to 1,296 - equal to the EFF Short List
* Issue a clear warning when using a smaller wordlist but do not prevent generation of passphrases
* Improve wording when removing custom wordlist
Replace a QVector for the wordlist with a QSet. This removes all duplicate entries in a given wordlist.
Thus, it hinders a malicious wordlist that has the proper length (>4000 entries) but with repetitions (effectively << 4000 entries) to be used and potentially create weaker passphrases than estimated.
Example:
List with 4000 items but only 64 unique words would lead to only 48 bit of Entropy instead of ~95 bit!
* Fix passphrase generator test
Previously, the test case was assuming the wrong regex. In particular, the default word list (eff_large.wordlist) contains several words that contain dashes. Adjust the regex used in the test to reflect this. This should fix rare test failures
