PSR-12 coding style

ignore PSR2 in the old form class

This class needs to be replaced with dokuwiki\Form in the future.

visibility fixes

First start at declaring visibilites for methods and properties. Still
missing: the parser/renderer stuff and the plugins

remove DOKU_INC checks

There is no need for this check, since these files should not have any
main code that is executed on direct call.

Fixes PSR1.Files.SideEffects.FoundWithSymbols

make Doku_Form members public again. fixes #1982

Various plugins access the form members directly currently.

replace some var keywords

This should fix some tests on PHP 7.1. The work is far from done, we
still have a lot of variables without proper accessibility defined.

I supplemented the existing comments on the methods in which there was not enough information to the standard phpDoc.

fixed editing of RTL and LTR scripts mix (including a lot of wiki syntax) being a mess

Bi-directionality is generally a huge pain in the arm, browser vendors
only added a few improvements quite recently. This fix only works in
Mozilla and Webkit currently. Affected syntax was links and media and all
opening and closing syntax (e.g. code and del and various plugin syntax).
