Port before_v0.60/fun folder (issue #221) (#835)

This PR is part of porting all old scripts #221 and ports `fun` folder

<details><summary>Summary</summary>

### star.nu
```yaml
from: before_v0.60/fun/star.nu
to: modules/fun/star.nu
```

### spark.nu
The script has already been ported. I've removed old version.
```yaml
from: before_v0.60/fun/spark.nu
to: sourced/fun/spark.nu
functions:
  spark: sourced/fun/spark.nu:1:spark
```

### life.nu
```yaml
from: before_v0.60/fun/life.nu
to: modules/fun/life.nu
```

### lisp_mode.nu
There is a problem with this module because `-` is not allowed in names
anymore, however `def "-"` is a valid syntax, but you will be unable to
call this function.
```yaml
from: before_v0.60/fun/lisp_mode.nu
to: sourced/fun/lisp_mode.nu
```


### nyancat.nu
I also fixed animation frames from https://github.com/klange/nyancat
```yaml
from: before_v0.60/fun/nyancat.nu
to: modules/fun/nyancat.nu
```
