What's New:
- Added C.LN1+X and C.E^X-1 functions. These are complex-capable versions of LN1+X and E^X-1.
- Fixed pasting of strings that start with E.
- Binary version: When converting binary to decimal, only use 17 digits when actually needed. This prevents 0.1 from turning into 1.0000000000000001e-1, for example.
- iOS version: Support for external keyboards.
