reformatting code with dokuwiki style
Clean up of code. Simplify parse and render function. Use ptype normal, and box is built with spans, so it has same embedding properties as {{images}}. alignment center added, similar to img. An alignment of img is autocopied to imgcaption. Removed getInfo functions.
Added Dutch, update other languages.
rewritten addEntryPattern
Now DOKU_LEXER_ENTER handles whole opening tag. Dropped DOKU_LEXER_MATCHED case, because that's only needed for addPattern matching. Cleaning image links by cleanID().
Added copying of img title to caption, when no one is set
Using metadata
Added phpdocs, only includes images, tables and links.
Added <tabcaption ..|..></tabcaption> and <tabref>
Splits imgcaption and tabcaption, so tabcaption has block p-type
Added referring to other pages with <imgref> / <tabref>
