  Log Message:
  -----------
  reworked parts of the install script

- allow to specify vz target dir on command line (handy for testing, but also handy fo real world usage)
- clone directly into the target dir instead of a temp dir and cp to target. this way, we have a fully working clone, i.e. you can later use git pull to update
- get_* functions now directly update the vz config
- check for php module pdo_mysql, we need this
- use dedicated php version check function
- fixed composer check (and output)
- only copy sample vz config if there is not already one
