Pyarmor

* Fix README.rst format error.
* Add title attribute to project
* Print new command help when option is -h, --help

use command **obfuscate** to obfuscate scripts directly. For
complicated package, use Project to manage obfuscated scripts.

Project includes 2 files, one configure file and one project
capsule. Use manifest template string, same as MANIFEST.in of Python
Distutils, to specify the files to be obfuscated.

To create a project, use command **init**, use command **info** to
show project information. **config** to update project settings, and
**build** to obfuscate the scripts in the project.

Other commands, **benchmark** to metric performance, **hdinfo** to
show hardware information, so that command **licenses** can generate
license bind to fixed machine.

All the old commands **capsule**, **encrypt**, **license** are
deprecated, and will be removed from v4.

A new document [src/user-guide.md](src/user-guide.md) is written for this new version.

* Remove unused files in distribute package

In this version, new obfuscate mode 7 and 8 are introduced. The main
difference is that obfuscated script now is a normal python file (.py)
other than compiled script (.pyc), so it can be used as common way.

Refer to [src/mechanism.md](src/mechanism.md)

* Introduce new mode: 7, 8
* Change default mode from 3 to 8
* Change benchmark.py to test new mode
* Update webapp and tutorial
