End Date Field Bug Fix

Correcting bug where an 'End Date' field would not be saved.

Negative Dates and Repeating Forms

Now properly handling situations where negative dates cause the calculated date to be from a previous year.
Allowing for saving dates to repeating forms, defaulting to the first instance.

Remove 'redcap_module_link_check_display' Function

Unneeded and incorrect definition of 'redcap_module_link_check_display' function removed.

Further Date Enforcement

More checks on valid date values being provided.

Fix for attempting to save repeated dates to off-form fields

New fix for trying to save multiple off-form date fields.
Side fix to not attempt to save date fields on forms that are locked.

Exception Refactoring

Now not depending on the mysql_xdevapi being present for exception handling.

Fixing a misspelling

Misspelled a call to "Exception" on a line.

Correction to Keep PHP 5.5 Compatibility

Previously a definition of the daysPerMonth array as a constant made the module incompatible with PHP 5.5. This has been changed to allow for compatibility. Version 1.5 is no longer supported and listed in the REDCap Module Repo.

Months Included

Now can use months as unit of date calculations instead of days. REDCap event offsets values will also be calculated in terms of months.

Event End Date Offset

When piping to events and using REDCap's event offset numbers, the end dates now properly read from the 'offset_max' value.
