v0.6

Intermediate release, with a lot of new code to handle N-grams
Also a lot of refactoring is done, for more clear and maintainable code.
This is work in progress still.

• TICCL-unk:

  • more extensive acronym detection
  • fixed artifreq problems in 'clean' punctuated words
  • added filters for 'unwanted' characters
  • added a ligature filter to convert evil ligatures
  • normalize all hyphens to a 'normal' one (-)
  • use a better definition of punctuation (unicode character class is not
    good enough to decide)

• TICCL-lexstat:

  • the 'separator' symbol should get freq=0, so it isnt counted
  • the clip value is added to the output filename

• TICCL-indexer:

  • indexer and indexerNT now produce the same output, using different
    strategies when a --foci files is used.

• TICCL-LDcalc:
  major overhaul for n-grams

  • added a ngram point column to the output (so NOT backward compatible!)
  • produce a '.short' list for short word corrections
  • produce a '.ambi' file with a list of n-grams related to short words
  • prune a lot of ngrams from the output

• TICCL-rank:

• output is sorted now
• honor the ngram-points from the new LDcalc. (so NOT backward compatible!)

• TICCL-chain: new module to chain ranked files

• TICCL-lexclean:
  -added a -x option for 'inverse' alphabet

• TICCL-anahash:

  • added a --list option to produce a list of words and anagram values
