Pyarmor

Pack obfuscated scripts by command `pack`

In this version, introduces a new command `pack` used to pack obfuscated scripts with `py2exe` and `cx_Freeze`. Once the setup script of `py2exe` or `cx_Freeze` can bundle clear python scripts, `pack` could pack obfuscated scripts by single command: `pyarmor pack --type cx_Freeze /path/to/src/main.py`

Pack obfuscated scripts by WebUI packer

WebUI is well reformed, simple and easy to use.

* Fix start pyarmor issue for `pip install` in Python 2

* Fix `pip` install issue in MacOS
* Refine sample scripts to make workaround for py2exe/cx_Freeze simple

* Fix typos in examples
* Fix bugs in sample scripts

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.

* Fix `pyarmor-webui` can not start issue
* Fix `runtime-path` issue in webui
* Rename platform name `macosx_intel` to `macosx_x86_64`(36)
