Fixed Scanner#skip() issue method when cursor is moving to the end of source
Simplified Progid node
Changed behaviour for bad selector processing, now parsing fails instead of selector ignoring
Fixed <id-selector> generic syntax
Added q unit for <length> generic syntax
Refactored syntax parser (performance)
Reduced startup time by implementing lazy syntax parsing (default syntax doesn't parse on module load)
Updated syntax dictionaries and used mdn/data instead of Template:CSSData
Renamed syntax.stringify() method to syntax.translate()
Simplified generic syntax functions, those functions receive a single AST node for checking and should return true or false
Added exception for values that contains var(), those values are always valid for now
Added more tests and increase code coverage to 98.5%

Changelog

Parser
- Added fallback node as argument to onParseError() handler
- Fixed raw consuming in tolerant mode when selector is invalid (greedy consuming and redundant warnings)
- Fixed exception in tolerant mode caused by unknown at-rule with unclosed block
- Changed handling of semicolons:
  - Hanging semicolon inside declaration blocks raise an error or turns into a Raw node in tolerant mode instead of being ignored
  - Semicolon outside of declaration blocks opens a Rule node as part of selector instead of being ignored
- Aligned parseAtrulePrelude behaviour to parseRulePrelude
  - Removed Raw node wraping into AtrulePrelude when parseAtrulePrelude is disabled
  - Removed error emitting when at-rule has a custom prelude customer but no prelude is found (it should be validated by a lexer later)
Generator
- Fixed performance issue with translateWithSourceMap(), flattening the string (because of mixing building string and indexing into it) turned it into a quadratic algorithm (approximate numbers can be found in the quiz created by this case)
Added support for a single solidus hack for property()
Minor fixes for custom errors
