Added download server preference to download parameter

Resolves issue  #7
Added functionality: the name of the download server can be passed as a command line argument (no longer a suffix of the download action), and is not considered an action, so omitting all actions but passing a download preference will still assume all actions.

An example commandline parameter could be 
```ruby processFile.rb ipg131226.zip reedtech``` which would assume all actions and a preference of reedtech

A minor regex error was also fixed in getting actions:
/^download|...|cleanup$/ should have been /^(download|...|cleanup)$/ in order to ensure that actions had no extra characters on the beginning or end. Previously, depending on where the action was in the regex, one could add characters to the beginning, end or both and still have it added to the actions array.

I didn't realize that pushing to my master would add to the pull request, so the following probably should have been pushed from another branch (though there were conflicts):

Added a catch-all substitution to remove newlines before reporting to csv file.  Removed all other newline removing substitutions.
