Fix moving share keys as non-owner to subdir

Close session for search

[OC8] Load javascript translations using standard web technologies

This fix gathers the share keys BEFORE a file is moved to make sure that
findShareKeys() is able to find all relevant keys when the file still
exists.

After the move/copy operation the keys are moved/copied to the target
dir.

Also: refactored preRename and preCopy into a single function to avoid
duplicate code.

Update doctrine/dbal to 2.5

Make search non-blocking.

adding console command to generate javascript translation files based on existing php translation files
read server side translations from json files

Moved search result type translations to search.js

Load JS translations earlier

Translations need to be loaded earlier to make sure that some JS files
like search.js get access to translations at this time.

This requires the template initialization to be moved to after session
initialization, because only after the session we have access to the
current language.
