Bandage v0.5.5

Features:

• Bandage now automatically chooses a 'Base pairs per segment' setting when a graph is loaded. Users can switch between this automatic value or a user-specified value.
• A more flexible system is used for determining node width using coverage. It allows for non-linear relationships, preventing very high coverage nodes from appearing excessively wide. A plot in the settings dialog previews the function between node coverage and node width.

Bug fixes:

• Performance fix for when node width is changed for a large graph.
• Performance fix for unloading large graphs.
