Plugin/WordMorph: several improvements

Browse Source 
- add 2880 variant words to wordlist
- morph generator skips words with same suffix
- default steps increased from 3 to 4
- default minimum word length increased from 4 to 5

Note that you can override default steps and word lengths via `start`.
