Windows command line problem

```
C:\Windows\system32>codecept install
Could not open input file: codecept
```

In codecept.bat file (https://github.com/Codeception/Codeception/blob/master/codecept.bat) need full path

```
"%PHPBIN%" "codecept" %*
```

Example phpunit.bat

```
"%PHPBIN%" "C:\Program Files (x86)\php 5.3\PEAR\phpunit" %*
```
