Version: 7

Features

New SVG processor.
HTML processor can also embed SVG TABs and including a rad viewer for them, too. You can easily navigate through the pages of your transcription. It could be quite nice when studying, remembering old transcriptions, etc. It can be awesome if you do not have a nice SVG viewer or want to produce a more device-independent output but keeping on some fancy stuff that would be dropped out in plain ASCII TABs.
New .part tag extension that makes possible to mark-up a more arbitrary song part instead of just the last written section.
Now shifted-repeats are possible by using: .repeat{<part>}{+|- <tones total> [.5]}.
For the sake of my sanity, now release notes are being stored into RELNOTES.txt, too.
Minor changes in syntax highlighting files related to v7 language extensions.

Some options related to tuning info were not being properly read when explicitly passed by command line, due to a pre-historic dummy typo ('tunning' instead of 'tuning' 🤦‍♂️) [commit-id#e537ef].
HTML and Markdown processors were writing incomplete TABS. The problem was in TXT processor, where sometimes NULLs were being written to output. [commit-id#6ffe59].
