Improvements

• Improvement: added Element.closest(), which walks up the tree to find the nearest element matching the selector.
• Improvement: memory optimizations, reducing the retained size of a Document by ~ 39%, and allocations by ~ 9%: 1. Attributes holder in Elements is only created if the element has attributes 2. Only track the baseUri in an element when it is set via DOM to a new value for a given tree 3. After parsing, do not retain the input character reader (and associated buffers) in the Document.parser
• Improvement: substantial parse speed improvements vs 1.12.x (bringing back to par with previous releases).
• Improvement: when pretty-printing, comments in inline tags are not pushed to a newline
• Improvement: added Attributes.hasDeclaredValueForKey() and Attributes.hasDeclaredValueForKeyIgnoreCase(), to check if an attribute is set but has no value. Useful in place of the deprecated and removed BooleanAttribute class and instanceof test.
• Improvement: removed old methods and classes that were marked deprecated in previous releases.
• Improvement: added Element.select(Evaluator) and Element.selectFirst(Evaluator), to allow re-use of a parsed CSS selector if using the same evaluator many times.
• Improvement: added Elements.forms(), Elements.textNodes(), Elements.dataNodes(), and Elements.comments(), as a convenient way to get access to these node types directly from an element selection.
• Improvement: preserve whitespace before html and head tag, if pretty-printing is off.

Bug Fixes

• Bugfix: in a <select> tag, a second <optgroup> would not automatically close an earlier open <optgroup>
• Bugfix: in CharacterReader when parsing an input stream, could throw a Mark Invalid exception if the reader was marked, a bufferUp occurred, and then the reader was rewound.
• Bugfix: empty tags and form tags did not have their attributes normalized (lower-cased by default)
• Bugfix: when preserve case was set to on, the HTML pretty-print formatter didn't indent capitalized tags correctly.
• Bugfix: ensure that script and style contents are parsed into DataNodes, not TextNodes, when in case-sensitive parse mode.
