Don't use too long words for passwords

[m-bra]

Example: "Bügeleisen4Sprechstundenhilfe" Is simply too long for a password.
Just don't use words from the wordslist that are >6 characters.

[TilBlechschmidt]

Currently, passwords are limited to 8+4+8 symbols in total. The example password provided got generated with the old word-list. The problem with a letter count below eight is, that the entropy drops rapidly. Whilst there are about 4000 words @ eight letters there's only slightly below 1000 nouns for six letters.
The possible fixes are:

1. Keep the maximum length at 20 symbols or eight characters per word
   or
2. Search for some more nouns that have got less than six characters

[m-bra]

|{1000 nouns} * {4 digit-numbers} * {1000 nouns}| = 10,000,000,000. We could search for more nouns, but I think ten trillion possibilities should be enough.
