Adjusted readme, specifying queues and statuses wont be necessary anymore, yay\!
All values are now properly escaped before they're added to the insert query
Merged pull request by mind3m into the 1.4.0 branch. Thank you! Closes #15
Added a version number that gets read in the menu. Makes it easy to see which version you are on
Removed debugging info
Removed the logging of setting log level to 0; spammed the log like crazy
Adjusted logging a bit
Fixed issue where the import would crash when hours worked or hours to bill wasnt available
Prevents a missing priority from generating an error, fixes #16
Edited the readme and bootstrap so it's explained where to edit your timezone settings in this new version. closes #17

Based on a comment from MattParr, I've removed the htmlspecialchars since it shouldn't be necessary anymore.
