Class fix for ACL\Login, DB\Extended\ArrayIO, edit_base.php

- edit base used useless regex for getting filename and dir from folder
  list. Changed to pathinfo() call to fix this
- edit_base.php and DB\Extended\ArrayIO fixes
On page order in edit we got errors because pk_name in ArrayIO class was
not init as empty string as it should be (is defined as string only)
- ACL\Login updates
Move all public functions to the public block.
Add public functions for base check Page/Base level to min level name
get acl array as is for now (will be extended with other calls for more
detail query)
Also clean ups in PHPdoc layout, long lines, etc
