Title: Use YAML::SyntaxError since ParseError does not exist under Psyck Yaml

implementations.

Running the synapse binary gives:
```
> synapse
/Users/jbellegarde/src/synapse/bin/synapse:40:in `rescue in parseconfig': uninitialized constant Psych::ParseError (NameError)
from /Users/jbellegarde/src/synapse/bin/synapse:34:in `parseconfig'
from /Users/jbellegarde/src/synapse/bin/synapse:46:in `'
from .bin/synapse:16:in `load'
from .bin/synapse:16:in `

'

```

YAML is an alias for Psych. Psych has SyntaxError instead of the Sick's ParseError.
