fix bignum issue

In the browser, sometimes the config for bignum wasn't being set up if (somehow
... still not sure how this is possible) you use bitcore without using
require('bitcore'). This would by pass the code that set the config for bignum.
Solution is to put the config for bignum in bignum itself (in the browser).

This fixes, in particular, an issue with base58 where it was depending on
bignum having the proper config.

Also I add the base58 tests to run in the browser which they weren't
previously.

And finally I add a small test for Bignum in the browser that makes sure the
config is set properly.

add some basic sanity tests for signatures and key generation

Signing a message with ECDSA involves using a random number, and this means
that two signatures should never be the same. This commit adds some basic tests
to Key.signSync and Message.sign to make sure this is the case. Also, a new
bitcore.Key should never have the same private key twice. This commit also adds
a basic test to make sure that is the case.

remove eval

eval is unsafe, and the way it was being used in Script and Script interpreter
was not a good enough reason. This commit removes both uses of eval, then
replaces all uses of OP_XXX with Opcode.map.OP_XXX since there's no reason for
those constants to be global.
