Release 2.5.7.0

This new version was finished many months ago but due to some unforeseen and tragic events in my personal life I could not find the time and motivation to release this at the time.

• Context menu reworked (use less resources, only show relevant items)
• Optionally hide address bar icon (#133)
• Optionally hide right click context menu 
• Update 3rd party libs: jQuery (3.7.0), DOMPurify (2.4.7), marked (2.1.3), DataTables (1.13.6)
