Add "number" type & timing offsets for DDR A/A20

[nchowning]

This PR creates a new patch type called "number". It allows users to put in a number (in decimal) for a value. These values are most likely going to always be 32 bit integers (4 bytes) but they can be more or less. This is especially useful for changing timing offsets in DDR. The min and max options are only enforced if using the up & down arrow buttons on the number input field. Later it might be a good idea to either telegraph the min/max values to the user better or enforce them in the applyPatch method.

I've also added timing offsets for all DDR A/A20 mixes. These values are:

• SSQ Offset: (Min: -1000 : Max: 1000) Arrow chart offset. Similar concept to stepmania global offset.
• Sound Offset: (Min: 0 : Max: 1000)
• Input Offset: (Min: 0 : Max: 1000)
• Render Offset: (Min: 0 : Max: 1000) Used to compensate for latency
• Bomb Frame Offset: (Min: 0 : Max: 10) Arrow explosion animation

Lastly, I added the ability for "union" patch types to have a tooltip set for the whole union - not just individual patch options inside of the union.

The use of the 32 bit view will limit the max size to 32 bits, i think. Also, we may want to support big endian numbers in the future.

Let's cross that bridge when we get to it, this patch is awesome.
