0.8.0

• Task comments can now contain markdown
• Fixed bug when running kanbn status -uq (would complain about trying to use .join(...) on a null value)
• Fixed bug when using kanbn edit command to add tags (new tags are now added correctly instead of ignored)
• Fixed bug when adding duplicate columns using kanbn init (adding the same column more than once wouldn't be recognised as duplicate)
• Task ids now support non-latin characters. Kanbn should generate task ids (and filenames) the same as before, but be aware that there might be edge-cases where it doesn't. In these cases, you might need to manually rename some files (and update their links in index.md accordingly). Use kanbn validate to quickly identify any issues
• Added more tests
