v1.9 - dev preview

Changes

• Reworked plugins (improved render times)
• Added global config (#16) - add a .blur-config.cfg in your blur.exe folder to be used as the default config. Adding an extra .blur-config.cfg next to input videos still works to override the global config.
• Added options
  • Video container
  • Interpolation mask
  • New interpolation preset 'default'
  • Option for custom interpolation strings
• Added the ability to set interpolated fps to a multiplier - e.g. 5x
• Added the option to add blur to path when installing (#11)
• Fixed some path errors
