In this version, there are three significant changes:
[Simplified WebUI](http://pyarmor.dashingsoft.com/demo/index.html)
[Clear Examples](src/examples/README.md), quickly understand the most features of Pyarmor
[Sample Shell Scripts](src/examples), template scripts to obfuscate python source files
* Simply webui, easy to use, only input one filed to obfuscate python scripts
* The runtime files will be always saved in the same path with obfuscated scripts
* Add shell scripts `obfuscate-app`, `obfuscate-pkg`, `build-with-project`, `build-for-2exe` in `src/examples`, so that users can quickly obfuscate their python scripts by these template scripts.
* If entry script is `__init__.py`, change the first line of bootstrap code `from pytransform import pyarmor runtime` to `from .pytransform import pyarmor runtime`
* Rewrite examples/README.md, make it clear and easy to understand
* Do not generate entry scripts if only runtime files are generated
* Remove choice `package` for option `--type` in command `init`, only `pkg` reserved.
