[LAA] MIDA 0.4.1 released

MIDA 0.4.1 released, changes: * dramatically improved efficiency, now very long compositions can be quickly rendered; * lexer: changed style of comments, shell-like comments adopted; * changed alias of notes: dièse is written now as `s` not as `#`, so middle octave is: `c5`, `cs5`, `d5`, `ds5`, `e5`, etc.; * now there are alias for all supported (in MIDI) pitches from 0 to 127, that is: from `c0` to `g10` (alias `c10` -- `g10` added); * changed alias of modulation signs, reason for such change is purely technical -- all alias now are predefined definitions, rather than syntactic sugar, so all alias must be valid identifiers; * identifiers can contain underline sign (`_`); * arbitrary number of files can be specified for loading (from command line, as well as from interactive REPL); * many purely technical changes that are difficult to explain concisely, but they should be mentioned, most important being addition of test suite and ability to generate source files from syntax trees; * added command line options: `--license` and `--version`. So, here are some syntax changes, this is because the project is still in flux, but it's settling down.
