Should task execution be case-insensitive?

[chrisdmacrae]

Right now task names are case sensitive. Worried this will cause a lot of confusion in some cases.

Consider the following maidfile:

## Example

```bash
echo "example A"
```

## example

```bash
echo "example B"
```

and I run:

maid example outputs example B

maid Example outputs example A.

My guess is that being case-insensitive would be a better design choice to prevent confusion and case based errors.
