Health Organizer Code

I have improved a little the way of decoding a code/description into a description/code via dynamic arrays to be able to translated them correctly.
Used then the new DB_DescriptionToCode and DB_CodeToDescription functions everywhere they are necessary
+ TfrmMain.SelectLanguage: calls DB_ClearDynamicCodeDescriptionArrays
- tDrugsPrescriptions: the When column has 2 caracters, not one
+ tDrugsPrescriptions: the start date must be <= the end date
* Removed from hor_messages all the messages needed for hor_messages_usb
- TfrmNavigationDrugs_Prescriptions: Fixed the title of the edit window
- TfrmEditDrugs_Prescriptions: Fixed the transaction property of the qFreeDefData: now the search inside the default data works! :)
+ TSaveThread.Execute: calls DB_ClearDynamicCodeDescriptionArrays
