Thread Tagging Improvements 1.0.8 Patch Level 1

Fixes for the JS that handles auto-tagging while creating a new thread:

• Don't rely on jQuery which has been removed in XF2.3
• Add tags with Tagify which has replaced select2

• Correctly escape the SQL for thread tag lookups
• If an SQL error occurs during Rebuild Job, log it and continue with the next one, instead of crashing/stopping
  • There is an option to disable these loggings under "Other", but we recommend keeping it on and reporting SQL errors raised to us
• Build the URL paths a bit better so the potential pages don't try to reach non-existing pages
