Market improvements

Browse Source 
-All external market apis have been normalized with a similar coding format, improved error handling with new wait times in between api calls to prevent abuse issues with sending too many requests too quickly
-All general market code has been reviewed and improved where necessary to help prevent sync issues
-Inactive markets are now removed from the markets collection on startup of the explorer to help prevent bloating the database
-The yobit api url has been changed to the new url
-The poloniex market has been updated to use the newest api
-The southxchange exchange trading link has been changed to the new url
-Miscellaneous locale string changes and reorganization
