Fixed some login issues and others

[MS-Jahan]

These are the fixes, worked for me and hope will work for others too.

• Removed restriction of specified reactions.
• Added system to manually enter c_name from browser cookie when needed.
• Redirect to homepage when Facebook wants cookie consent (this broke login system for some people).
• Added new regex to grab fb_dtsg from server response.
