Added formatting rules for Eclipse.

There were two conflicting formatting issues I could find.

1. Whitespace on blank lines.
2. Whitespace using casts.

For both of these there’s been two conventions.
I’ve used the one that causes the least changes in the source.
ie: Strip whitespace and add a space between the cast and object.
Applied formatting rules to Bolts and BoltsTest.
