Don't crash on prompt cancel.

Don't crash when HSV_VALUE == 1

256 isn't a valid value (valid values range from 0-255, inclusive).  So the correct constant to multiply by is 255.

Use possessive 'its' instead of contraction for 'it is'.

Update delete icon to Material Design

Google has always been suspicious of the old trashcan artwork.  It came from MIT's Open Blocks, which despite claiming to be open source is known to have some copyrighted resources (click sound is stolen from MS Windows 95).  A thorough search could not locate any known origin for the trashcan, so we used it, warily.
