Update drone.yml to 0.5

Fix failing preview unit tests

Choose button remains disbaled for httpd/unix-directory

Fix codesniffer complains on some apps

This is not correct. Hence in this patch we validate
if the mimetype is 'httpd/unix-directory'. If so we
don't disable it.

This patch addresses solution for issue: 26034

replace he with they in readme

Cache the build ControllerName

Cast query result to int

Move remote_shares OCS endpoint to AppFramework

Often a route.php file will have many N routes but only M controllers.
Where N >= M. Which means that in most cases the ControllerName will be
converted multiple times. This is of course far from ideal.

Note that this is per app so the cache will contain at most N entries.
Which is not to bad.

deleted files, fix mimetype detection

Else we never create the default address book

detect the correct mimetype of the files in the trashbin, therefore we have to check the filename without the appended timestamp

Don't print exception message in HTML

Filter more mimetypes

The exception message is potentially influenced by user input and could thus be confusing (e.g. somebody could try to open a file like "Please send a mail to support@foo.com", and then the message would include that string.

It is thus reasonable to not show the exception message by default. Also for the browser view I added an `exit()` at the end, as otherwise the XML exception would be attached.

There's no need to allow more than those defined mimetypes for images.
