enjsms2: initial commint of new branch; pure
readme: fix typos
package.json: fix repo url "for computers"
enjsms.htm: load app_front.js only if it exists; clear onload handlers
app_front.js: added; nw: tray setup, extjs loading
app_front.js: config file loading
Merge branch 'master' into enjsms_serialport_node-webkit

I will going to use only `node-webkit` to run and control
other processes (i.e. `mongodb` and other `node`s).

Main control room is on local display of node-weblit.
Working ones are handled by `express`.
Application is organized as modules for:
 * user/role management
 * background process management
 * actual application
 * reporting on users
 * (more)

This is going to be enjsms2.
