Fixed minor typo in translation.rst
Made 'Admin'/'Admins' the consistent style for referring to a SonataAdmin Admin class
Updated console command docs and tweaked GenerateAdminCommand:
* expanded sonata:admin:generate docs
* switched order of list and explain in docs, since you need to list first before you know what to explain
* refactored GenerateAdminCommand::getAdminServiceId() so it only strips the end off Bundle names that end in "Bundle"
* edit for readability
Updated console docs:
* added short note about sonata:admin:generate-object-acl
* updated inline documentation in GenerateObjectAclCommand.php
Updated advance.rst:

* fixed table formatting (old version was hidden)
* fixed 'security_feed' typo, the example is actually about 'project'
* moved the RouteBuilder customisation info to its own sub-section
* moved the generic customisation text above RouteBuilder
* tidied up the generic customisation example
* tidied up comments in sort-order section so they should display better (without line wraps) on sonata website
Cleaned up and expanded batch_actions.rst:
* added note about two options when adding a new batch_action
* added note about what the merge example is trying to do and when it's available
* edited code blocks to prevent line wraps on sonata website
* updated list__batch.html.twig example to reflect latest contents
* added link to Symfony bundle extension docs
Updates to security.rst:
Fixed indentation issues which were creating rogue DLs and list levels
Minor spelling/grammar edits (unlike French, English has no spaces before colons)
