This commit adds the ability to add multiple IF
conditions in an IF block by using `if else`:
```
if x {
...
} else if y {
...
} else if z {
...
} else {
...
}
```
I decided to change the data structure that represents
IFs because it was very limited, only allowing for
a condition, a consequence and an alternative consequence.
Now IFs are a list of `Scenario`, made of conditions and
consequences. If we encounter a bare `else` we set the condition
of that scenario to true, so that it always evaluates to true.
One funny thing that this structure does is that it allows
for code like this:
```
if x {
...
} else {
...
} else if y {
...
}
```
(`else` before `else if`)
I honestly don't mind having this (it's a fun easter egg), but
we might want to raise a parser error later on if users find it
annoying.
