v0.7.0

• The cluster and addquotes commands now have an autofinder feature: if they are not specified, the .kl, and .diagnose files are automatically found in the current folder. (#5)
• After clustering, indicate which files have been modified. (#35)
• Automatically checks for newer versions when running any command (can be disabled with the --no-update option).
• AP is now a synonym for the command anchor. (#24)

Minor changes:

• Fixed bug #43: hyphenation is now properly handled by cluster.
• Fixed bug #36: if the same .kl file in given multiple times, ignore the copies.
• Fixed bug #39: the imperfection of the stemmer was causing some problems when computing the distance between notions.
• Switched from using the os library to pathlib.
