making pyagregator runnable by apache

* adding bootstrap module for basic import
* redoing logging (config, proper use of the logging module)
* making secret part of config (random wouldn't work with apache since
  it uses different instances of python)
* making server entry point not executing application if just imported
* not writing file for opml when we can read it from memory
fixing parsing for already quoted url as well
Merged in jaesivsm/pyaggr3g470r (pull request #2)
