private_download 6.x-1.4

Bug fixes

• #1389810: Does not implement hook_file_download the right way and hijacks path system/files
• Do not by default serve private files as cacheable

New features

• Introduces hook_private_download_access() that allows modules to alter permission to access private files. See private_download.api.php about this.
• Allow downloaded private files to be displayed within the browser window

These 2 new features introduce corresponding new settings in the admin form.

Misc

• Removed the FILE_DOWNLOADS_PRIVATE check: even under a full private environment, Private Download works as expected.
• Moved the admin form to a separate file
• Did some code clean-up
