22b87325d7 make Dark Wallet buffer/string formats the default 
and rename the old functions to "bitcore buffer" and "bitcore string"

96df77429f add support for Dark Wallet-style addresses 
These functions are prefixed DW which stands for Dark Wallet. The code for the
Dark Wallet address format can be found here:

https://github.com/darkwallet/darkwallet/blob/develop/js/util/stealth.js

Note that I deliberately support only the simplest possible format, which is
where there is only one payload pubkey and the prefix is blank. I should now go
back and replace my old toString, fromString, toBuffer, fromBuffer functions
with these Dark Wallet versions, since they are much more well-thought out than
mine.

9b8ce05b15 BufferWriter().toBuffer convenience method 
It does the same thing as .concat(), but may be easier to remember, since the
rest of the library uses the ".toBuffer()" convention

e984736736 allow bufs in constructors 
For Transaction, Block and Blockheader. This is a convenience so if you happen
to have the buffer for one of these, you can make a new one like this:

Transaction(txbuf);

Rather than having to do this:

Transaction().fromBuffer(txbuf);

followed by a single pushdata OP with not more than 40 bytes.

cc3196085f add .hash() function for a block 
This is the plain old hash, which is a double sha256. The id of a block is the
reverse of this.

cfd509f859 make receivePubkey compatible with dark wallet 
I had been using this formula for the receiveKeypair:

scanKeypair + payloadKeypair + sharedKeypair

However, Dark Wallet uses this formula:

payloadKeypair + sharedKeypair

It is not actually necessary to add the scanKeypair in order to have all the
features of stealth addresses, at least as far as I can tell. So in order to
bring my implementation closer to Dark Wallet's, I have removed the scanKeypair
from this calculation.

f6a8878aa2 Varint class 
...will be useful in transactions. Note that we already have a primitive
understanding of Varints in the BufferReader and BufferWriter classes. However,
the new Varint class is a varint object which actually depends on BufferReader
and BufferWriter for reading and writing varints. This class is for keeping
track of the raw buffer that is read in from a buffer.
