Larger pads for certain components

[mDubovsky]

The TLP290-4 was a bit hard to solder with a soldering iron due to the leads obscuring much of the soldering pads.
It was almost impossible to solder the inductor in the 5V supply as the inductor covers the SMD pads completely.
It would be beneficial to edit footprint of these components and enlarge the pads for easier assembly.

I have to agree that the inductor is a bit harder to hand solder (i just got used to it), the footprint is for reflow soldering. I will adjust it
