* YUI Bugfix: Newlines before and/or after a preserved comment `/*!` are not removed (we leave just 1 newline). YUI removed all newlines making hard to spot an important comment. * YUI Bugfix: Spaces surrounding the `+` operator in `calc()` calculations are not removed. YUI removes them and that is wrong. * Better numbers & colors compression. * Added `~` & `=` to the things that should have no spaces before or after them. * Improved regexp for issue #2528146 * Improved regex for matching a colon before a number to avoid matching colons in selectors -> from [\:\s] to ((?<!\\\\)\:|\s) * Added AjaxMinifier 4.47 unit tests * Unit tests script rewritten. Unit tests output is HTML now and if a test fails the difference between the generated output and the expected output is clear at first sight thanks to the finediff library and the github styles applied. * Updated README.md
