linecook init cannot handle no args or '.'

Linecook init isn't smart enough to figure out it should generate in the pwd.

mkdir dir
cd dir
linecook init .
already exists: .../dir

Even worse:

linecook init
/Users/Simon/.rvm/gems/ruby-1.8.6-p399@chiangs/gems/linecook-1.1.0/lib/linecook/commands/command.rb:50:in `process': wrong number of arguments (0 for 1) (ArgumentError)

Currently difficult to fix. The init command is not a true generator - it doesn't know how to handle conflicts. At present it avoids the issue by not overwriting existing directories and providing the --force option to remove the existing directory and then go forth.
