Enhance package.json, "devDependencies"

[samchon]

To build the TGrid, users must install typescript as a global module by themselves. Also, to build the API Documents, users must install typedoc and typedoc-plugin-external-module-name globally, too. Those actions are not automated and sometimes make users annoying.

To automate those actions, it would better to write those modules in the devDependencies.
