Add a team resists/weaknesses table to the teambuilder

[jjones21]

Of course external sources exist for this same purpose but i think it would be very useful to have it built into the showdown teambuilder. Otherwise you need to enter the full team of pokemon into another site or app, and every time you want to change the team you would need to update both teambuilders. Its more of a convenience thing than anything, but i would greatly appreciate it.
