Dynamic loading and creation of wallets

Previously, wallets could only be loaded or created at startup, by specifying -wallet parameters on the command line or in the bitcoin.conf file. It is now possible to load, create and unload wallets dynamically at runtime:

• Existing wallets can be loaded by calling the loadwallet RPC. The wallet can be specified as file/directory basename (which must be located in the walletdir directory), or as an absolute path to a file/directory.
• New wallets can be created (and loaded) by calling the createwallet RPC. The provided name must not match a wallet file in the walletdir directory or the name of a wallet that is currently loaded.
• Loaded wallets can be unloaded by calling the unloadwallet RPC.

This feature is currently only available through the RPC interface.
