Basic unit renamed from Note to Text.
New modular text-parser, internal to Logarion, for generic notation parsing. The default input format is now a much plainer text.
Eliminated Meta module and generally lib/ modules.
New Store interface, with additional information from Store. For example the converter can now check filesystem dates. Changed to filesystem hardlinks for tracking publications & indexing, instead of categories. New commands `publish [-i]` and `deindex [-u]`. Categories are ignored now.
Logarion created texts have part of the UUID instead of a counter in their filename. New -i, --interactive flag for interactive creation & publication.
Logarion's index re-written in Messagepack format. Removed `indices` command. They are generated during `convert`.
