Update:
- added some new integer sequences (notably `İπ` is the infinite list of digits of pi)
- `ḣ`and `ṫ` on lists now avoid returning the empty list (@Mr.Xcoder and few others might be happy about this)
- new builtin: `Θ` adds a default value to the beginning of a list. Default values are usually falsy ones. `ΘN` is the list of non-negative numbers, `Θḣ` is the old behaviour of `ḣ`.
- new overloadings: `D` now works on lists repeating them twice, `½` works on lists returning a list of their two halves
