Tab Tab Tab Tab

Fixes:

• Made it so that the 'Next' button on the final screen actually does something
• Fixed the ordering for an odd number of combatants

Improvements:

• Added Tab functionality so you can press tab between input fields
• When you press return/enter the game will do the function associated with the Next key

Overall, Unity UI is difficult for me. I have great respect for UI programmers. When just figuring out how to get one field to link to the next so that you can press Tab to move between them is difficult, I both appreciate the flexibility of the system, and curse the lack of 'user friendliness'. I am become n00b.

At least though, this is at a line where I would consider it in Beta, rather than Alpha, I just haven't gotten around to renaming the files et al.. This was never supposed to be a super polished product, this is mainly for internal use, the only reason it's here is because I couldn't find decent software to run a Swiss style tournament when I was looking for it, maybe this could help someone else.
