0.1.9-edit bladder capacity!

I received a lot of anonymous feedback through the feedback box, and saw that there are several people wanting to define their own bladder capacity instead of using the one generated by the app, so I added that in today's update!

In this update, you can define your bladder capacity by clicking on the pencil icon next to the bladder image. There you can:

• Set a custom bladder capacity (between 100ml and 2000ml).
• Clear the custom bladder capacity to use the auto-generated one.

I hope you like it, please feel free to give feedback or suggestions!
