This should fix the test problems errors in #1527. When requesting a
HTTPS URI from a HTTP only proxy, the initial connection is *not* TLS
secured. The URI scheme is only relevant when directly connecting.

This also changes the (wrong) assumption that everything on port 443 is
always TLS secured. Only the URI scheme should decide that.

This is to ensure that we use SSL/TLS if a custom port is defined an no
proxy is used.

Fixes #1526

Form TagCloseElements should conform to expectations of functions inherited from Element

Reflection based method export for remote plugins

make reuse of mediamanager popup easier

add support for new Django hashing methods

obfuscate auth passwords in config. fixes #1487

Translation update (ro)

The header() method of PHP is vulnerable to HTTP Response Splitting
attacks.

This change makes sure the URL passed to send_redirect (and thus to
header()) does not contain any control characters that would be needed
to execute such an attack.

Cleaning input is recommended anyway.

Translation update (pt-br)

missed a line in my last commit

This makes it easier to create tabs with an active tab (no need for
additional markup)

Translation update (ko)

Fixes for the FR translation

A few fixes.

multicheckbox without extra string input

remoteuser - Patch for default setting and improved checking in hasAccess()

we already do it for other passwords, so it makes sense to do it here as
well.

#1477:Search heading still displayed although search disabled

use getNS() call instead of dirname()

New Python Django application default to PBKDF2 with SHA256 as a
password mechanism. This adds support for that mechanism in our
password hasher class. This will be needed in the tests for the new
PDO auth plugin.

Fixes #1480

* master:
  refactor page saving and introduce COMMON_WIKIPAGE_SAVE

This makes sure the provided callback is using alphanumerics only. I'm
not sure this is needed, but better safe than sorry.

refactor page saving and introduce COMMON_WIKIPAGE_SAVE

because we actually want it in this branch ;-)

This reverts commit 38a2174b.

this was an accidental commit to master

This reverts commit f7f7fb6c.

This introduces a mechanism to override what happens when a media item
is selected in the media manager popup by providing a callback name in
the URL. The default implementation just does what
dw_mediamanager.insert did before and calls insertTags()

As discussed in #1471, an uninitialized variable will always be
implicitly created when passed to the blank() function. Calling isset()
is thus a no-op. A warning about this behavior has been added to the
function comment.
