X-axis forgiveness

For phetsims/qa#220
Design question. When dragging masses on the springs down I've often had the masses come off the spring. I know there is a balance between making sure the mass stays on when wanted and comes off when wanted, but I was wondering if keeping the mass on the spring for a little bit more of the x direction might feel better.

This the RELEASE_DISTANCE can be adjusted fairly easily, so I will leave this up to @arouinfar to review and determine if adjustments need to be made.

@Denz1994 let's bump RELEASE_DISTANCE up to 0.12.

[Denz1994]

The RELEASE_DISTANCE has been increased. This will affect MAS and MASB so it should be reviewed in both sims. This change should be included in the next MAS maintenance release.

Assigning to @arouinfar to review.

Looks good to me @Denz1994!

@KatieWoe, how's master feeling to you?

[KatieWoe]

I think it feels better. Give me a chance to check on iPad really quick.

[KatieWoe]

I think I like it a bit better, but I could also see an argument being made that the masses are harder to take off the spring, though not much. @Denz1994 I'll leave it to your discretion.

[Denz1994]

I'll keep the increase to the RELEASE_DISTANCE. I've run into similar problems with accidentally removing a mass when fully extending the spring. Thanks for the input @KatieWoe.

This change should also be included in the next Masses and Springs maintenance release and will mark as such.

When looking at dev.1 the spring behavior being wrong interfered with testing. On master I noticed that the distance to the left of a spring the mass was released was different from the distance to the right of the spring.
