#7 Option to leave custom colors in Hex and a couple of others

[Greg]

Working a sticker and noticed when I reopened a file, the 0x2... colors were changed to base ten.
I hadn't noticed it when I last saved. I find it easier to recognize custom colors in hex.

edit action to loose trailing whitespace (right-trim) - alternately could be part of 'trim blank lines'
edit action to remove leading zeroes for smaller files ( 0.25 -> .25 and -0.25 -> .25). could be option on the rounding settings.

(I'm really liking this editor!!!)
