New year, new build!

I've done quite a bit in this one. The biggest addition here being that the calculator now serializes your builds so they can be shared around. For example, this build should contain 3 skills in balanced and four down the tank tree.

Also, if anyone an verify, what is the pattern for receiving skills, 1 point on every even level starting at 6? Is it 17 points total?

Other less obvious improvements are much improved filtering options to let you easily change searches, and what seems to be the completion of the Equipment functionality! The database can now support equipment with primary, secondary, and on-equip bonuses, as well as the trickier devices that contain other devices (like deployed turrets and the grenade launcher).

This means I'll be moving to finish up skills next and thanks to sedateflame's contribution, I'll probably start with Recon  

I've also begun activating caching on some pages, please let me know if anything looks broken!
