Release 0.5 alpha

This release includes some major refactoring to make the application more reliable and better integrated with Specter.

• Searches different libraries automatically to find Specter
• Installation is easier with pip install
• Included full transaction list
• Included returns in any fiat currency selected by user

This version still needs some testing and may not run in all systems. It was tested on a Linux based machine with Specter Server running and installed via pip install.
