Added the normal LNCS quote style

you should include the splncs03.bst file(default exists)!
add splncs.bst whose citation style is in order!

* `splncs03.bst` use ***alphabetical*** order
* `splncs.bst` use ***normal*** order
added .gitignore

ignore all the other files except .tex?
updated .gitignore

except most of the useless files. :)
