docs: Sets whether colliding resources should be overwritten during the import for a
  specified import implementation.<p>
  
  v1 and v2 imports (without resource UUIDs in the manifest) *MUST* overwrite colliding
  resources. Don't forget to set this flag back to it's original value in v1 and v2
  import implementations!<p>
  
  This flag must be set to false to force imports > v2 to move colliding resources to
  /system/lost-found/.<p>
  
  The import implementation has to take care to set this flag correct!<p>
  
  @param overwriteCollidingResources true if colliding resources should be overwritten during the import
