README change: corrected the "Run the Arquillian Tests" section

[rsmeral]

• emphasized the importance of Arquillian
• corrected and minimised the usage of the word "container" throughout the section, as it can be ambiguous
• described configuration options of arq remote container and emphasize that it can actually be used to run tests on different machines
• corrected usage of "test/resources/arquillian.xml" to "src/test/resources/arquillian.xml"
• the "managed container" section incorrectly contained mentions of a remote container
• mentioned the possibility to use JBOSS_HOME env var
• I found the managed container section too verbose, I think there's no need for two code snippets, one is plenty

[rsmeral]

These are merely suggestions, based on my feeling that the section was sometimes a bit unclear, other times too verbose. WDYT?

Other than the rendering issues, I think this is great! I'll make the same change to the EAP quickstarts. Thanks!

This is in the section: Test the quicksrtart on a remote server. It states:

• Arquillian's remote container adapter expects a JBoss server instance to be already started prior to the test execution.

This tells me: You must Start the JBoss server as described in the quickstart README file.

Merged.
