remove deplicated getInfo()

getInfo() has replaced by plugin.info.txt since DokuWiki 2009-12-25
Lemming.
use plugin config variable "dt_fancy" instead of  DL_FANCY
plugin config variable "stylename" for dl element

apply default class explicitly to dl element. use blank to render most
simple dl list.
Add basic syntax tests.
Change stylename to classname, fix up docblocks, and extend testing.
Code style fixes. Nothing semantic.
More tests, including some that are now failing.
[Refs #2] Another list test. And remove a typo in the preformatted one.
Major rewrite of handle() to better facilitate lists within definition list items

The plugin now completely writes its own plugin calls.  Both DT & DD tags use
DOKU_LEXER_ENTER & DOKU_LEXER_EXIT states (rather than the previous DOKU_LEXER_MATCH).
This change allows the plugin to work better with DokuWiki's own EOL & paragraph
handling and avoids invalid html which could occur previously (e.g. when lists where
included within DD items).

PHP class code is also updated to use visibility properties.
Minor changes to improve white-space handling
- ignore any spaces after syntax triggering characters
- include a new line after opening <dl> tag
Update tests to match actual white space behaviour
Rework tests making the code slightly simpler & replacing '\n'
with NL constant.
New release.
