schema v0.7.0

Added

• MySQL support. mysqldump output and hand-written MySQL DDL now parse: backtick-quoted names, /*!...*/ comments, DELIMITER blocks, inline KEY / UNIQUE KEY / FULLTEXT KEY / SPATIAL KEY indexes (unnamed ones are named the way MySQL names them), AUTO_INCREMENT, unsigned, column and table COMMENTs, ON UPDATE, CHARACTER SET, generated columns, CREATE ... DEFINER=... VIEW, triggers, and ALTER TABLE ... ADD INDEX / DROP INDEX / DROP FOREIGN KEY / MODIFY / CHANGE. The dialect is detected from the file, so diffs, layouts and every other feature work as they do for Postgres.
• The playground works on phones: the sidebar becomes a drawer (☰), the table panel covers the diagram, and the top bar fits.

Changed

• SQLite's internal tables (sqlite_sequence, sqlite_stat*) are no longer drawn.
• View dependencies are also found through parenthesised joins (FROM ((a JOIN b) JOIN c)), which pg_dump writes for views with several joins.
• A file that yields no tables now gives a warning instead of an empty diagram with no explanation.
