html: dash is allowed in tag names (thanks @tjgrathwell!) (#173)

Allow passing a theme name as a string to :inline_theme (thanks @Arcovion)
Add :start_line option for html line numbers (thanks @sencer)

For tableized line numbers, the table is no longer surrounded by a <pre> tag, which is invalid HTML. This was previously causing issues with HTML post-processors such as loofah. This may break some stylesheets, as it changes the generated markup, but stylesheets only referring to the scope passed to the formatter should be unaffected.

Add the :inline_theme option to Formatters::HTML for environments that don't support stylesheets (like super-old email clients)

php: Properly lex variables in double-quoted strings and provide the correct token for heredocs (thanks @hrysd!)
Add a :wrap option to the html formatter (default true) to provide the <pre> wrapper. This allows skipping the wrapper entirely for postprocessing. (thanks @cjohansen!)

version 0.3.6: 2013-05-27

fixed bad release that included unfinished D and wdiff lexers :\

version 0.3.5: 2013-05-24

version 0.2.7: 2012-10-22
