Add packages required to build the library to dependencies

This allows other packages to depend on the ol3 package and get the build tools (devDependencies are not installed when they are transitive dependencies).  The justification here is that the ol3 package becomes useful to other packages when you are able to run the build.js task.  For this task to run all of its dependencies must be available.
For jsdoc to find plugins, we need to set the cwd

This allows the `build.js` (and the exports from `generate-info.js`) to be run with a different working directory.
Make our build configs more portable by using the default src config

If a `src` config is not provided, by default, all of the library sources are included.  There is some special handling in the build task to make sure all library sources are included regardless of the path to the build config.  When someone includes a `src` config, path patterns are assumed to be relative to the current working directory (unless overriden with the `cwd` config).  So, when you use the `src` config, your config is no longer portable.
