Patch notes - assorted bugs

Quick fix for a variety of small bugs.

• Worm 'Ram' and Polearm 'Charge' now cause knockback in the direction of caster movement, even if the charging unit ends up on the other side of the hit unit.
  
• Fixed a bug with Polearm 'Charge' that was preventing it from displaying tooltips dynamically added by equipment, e.g. the +knockback from a pearl.
  
• Fixed a bug with Polearm 'Charge' that was causing it to 'hit' the targeted unit even if the Polearm's charge would be blocked.
  
• Removed newlines from status effect descriptions. Multiple effects from one status are now separated by commas.
  
• Fixed a bug with Freezing Ray 2's damage not upgrading.
  
• Bewitch 2 and 3 can now be self-targeted and only hit enemies.
