Merge pull request mongoose-os#8 from mongoose-os/mdash

Add mos mdash-setup

Add warning and error manifest keys

These can be used in apps and libs unconditionally:

```
warning: I'm a deprecated lib, please don't use me.
```

```
error: I'm a bad lib, don't use me.
```

Or conditionally:

```
conds:
  - when: build_vars.FOO == "BAR"
    apply:
      error: This won't work, don't do it
```
