v1.0.6

• Automatically add "ans" if first button is bin op,
• allow omitting leading zero,
• add kcal/Cal units, round output of trig functions to zero if small

v1.0.5-7

Added changelog for android version 9. APK should be the same.

(I'm not actually sure if a separate release is needed for this, I just wanted to make sure that F-Droid would get to see the version 9 changelog.)

v1.0.5

• switch to material design
• use AboutLicenses instead of the GMS one, which is not allowed in F-Droid
• misc cleanup
