Subject: [PATCH] Libraries read-only in IDE links
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

«IDE-Link kopieren» marks the block's libraries (loaded by URL) as
readOnly, so the IDE (with glpython-editor v0.1.19) shows them with a lock
and doesn't let them be edited, renamed or deleted - as «Datei ansehen»
shows them here. A block file with a library's name replaces it and stays
editable.
