[FR] Tangling code blocks inside encrypted subtrees

[Ihor Radchenko <yantar92@posteo.net>]

Hello,

Currently, Org mode never tangles code blocks when they reside inside
encrypted subtrees. Never means that such code blocks will _not_ be
tangled even if encrypted subtree is temporarily decrypted via
org-decrypt-entry/org-decrypt-entries in the current buffer.

The current approach is indeed safe as it prevents leaking potentially
sensitive information. However, it is sometimes necessary to tangle the
code blocks from inside encrypted trees as well. For example, if the
file is a literate Org config - the whole point of such config is to
tangle it, including encrypted parts.

To allow tangling encrypted code, we may provide a special tag :TANGLE:
or maybe a special heading property, like :TANGLE-ENCRYPTED: yes. If
such property is set in the encrypted heading, Org will decrypt and
tangle the code blocks inside.

WDYT?
