Geshi Option parsing

fallback for new section editing. fixes #2311

Prevent HTML and JS injection in section names

Before this change, HTML and some JS code (as far as it was not escaped
by json_encode) could be injected into the output as the closing pattern
that is checked by the regex is not escaped in JSON (see test case).

The displayed message now shows the target that was passed, which should
help identifying the troubling plugin.

Instead of failing, we fix the data ourselves - this code will be
removed in the future.

DokuHTTPClient: Add handling for 204: No Content responses

Translation update (hr)

This fixes a bug that would occur if the DokuHTTPClient receives a 204
response, e.g. as a result for a request to delete something. It would
still try to read the body, which fails, thus producing a timeout and
finally throwing an exception.

This fix instructs the HTTPClient to not read the (not existing) body if
it receives a 204.

monkey patched GeSHi/geshi-1.0#104

Quotes are now optional, the options are spearated by space

bring back the namespace in braces for pagelookup results

While it's generally frowned upon testing privates, it can often be
useful and the easier way to write tests. Eg you want to test something
complicated method that is important, but you do not want to expose it
directly to other classes...

This new method uses reflection to make access to such methods possible
from within tests without the need for intermediate classes.

This was unintentionally removed in
4eab6f7c

It also should now be clearer what the code does.

This fixes #2305

As discussed in #1933

shorter names are more in line with what we already use, makes less
layout problems in the documentation and is easier to type when telling
people about it.

This fixes broken nested section edit buttons which were causing
invalid HTML code. The pattern has to be 'not greedy'. Fixes #2304.

switch extensions if stylesheet in style.ini doesn't exist (backwards compatibility)

This should give us some backwards compatibility for changing files in
dokuwiki template from .css to .less

This way template authors get a warning to adjust their template, it
won't break right away.

This should prevent breaking search pages in other templates due to
pull request #2286 .

feat: canonically provide $ACT to javascript

This is a more consistent place relative to pageinfo()

New CLI Plugin Type

Better core search

PWA manifest and new @ini_theme_color replacement

json_encode is available natively since PHP 5.2

This should make their purpose more obvious.

They are now named min and max respectively, which is hopefully less
cryptic.
