This commit modifies the way the data paths are handled. Since there will ultimately be more data associated with each network than just the block database, the data path has been modified to be "namespaced" based on the network. This allows all data associated with a specific network to simply use the data path without having to worry about conflicts with data from other networks. In addition, this commit renames the block database to "blocks" plus a suffix which denotes the database type. This prevents issues that would otherwise arise if the user decides to use a different database type and a file/folder with the same name already eixsts but is of the old database type. For most users this won't matter, but it does provide nice properties for testing and development as well since it makes it easy to go back and forth between database types. This commit also includes code to upgrade the old database paths to the new ones so the change is seamless for the user. Finally, bump the version to 0.2.0.
