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.

bring back the namespace in braces for pagelookup results

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.

This is useful for anonymously useable forms, like the search.

Pressing enter in the small quick-search-box while it was empty resulted
in a search for the current pageid.

Since we no longer change the page during a search, using the "show"
menu item to return to the current page makes more sense.

This way they can be cleanly influenced by the plugins instead of having
to modify global state.
