v1.2.0

Added

• Perform initial variable minification before starting optimization
• Constant folding: constant integer expressions are evaluated by
  pakettic, in case they compresses better
• More detailed reporting of the crunching results

Fixed

• Spaces between tokens were not always printed even when needed
• Hex numbers with fractional digits had the fractional digits printed in reverse
• Hex numbers with an exponent raised an error when printed

Changed

• The default compression level is now -z0; our benchmarking does not
  show significant advantage over -z2 (only 0.2% over the test corpus),
  yet it's almost 3 times slower. Use -z2 and higher only when you are
  desperate and absolutely need that last byte.
