#52: Automatically set the label separator to the list separator when csv, etc. is selected with @sites (or other multi-site commands)
#52: Simplify code to automatically set the label separator.
Add suggestions from #56.
drush_valid_drupal_root() requires only a file called includes/common.inc to match a Drupal directory, which causes problems when this file pattern appears elsewhere, in non-Drupal root contexts (e.g. in module_builder module).
Refactor drush_valid_drupal_root() to avoid a second function with checks.
Make _drush_add_commandfiles() more robust at detecting and avoiding double-loading Drush commandfiles.
Fix bug in drush_tarball_extract that caused the wrong thing to be returned in the file list if $destination was specified when a zip file was extracted.

Fixing cygwin path conversion (See https://drupal.org/node/2036001)
Split table list returned by _drush_sql_get_db_table_list() correctly when on windows.
Exploding the newline-seperated string of table names only on newline characters (\n) leaves all corresponding carriage return (\r) chars behind. confusing all checks performed directly on the array, such as in_array. As e.g "sessions" != "sessions\r", $skip_tables oder $structure_tables will only contain the respective setting's last element.
README.md changes from the master branch: support section, notes on assigning issues, moving usage up, add links to old drupal.org issues.
Add CONTRIBUTING.md from the master branch.
Remove dead code from site-install. sqlite doesn't need special handling here as sql-drop already supports sqlite.
Add --field-labels option, so that users may omit field labels from command output if they do not want them.
Fix #109. drush status's 'PHP configuration' should reflect the setting of the DRUSH_INI environment variable.
