Move upload_max_filesize warning to system check
CRM_Utils_Number::formatUnitSize() function does a check for whether the
upload_max_filesize in PHP is smaller than the maximum upload size in your site settings.
- The message calls the php.ini setting "upload_max_size", which will lead people astray.
- This really should be a system check that you see well before you are about to upload something.
There's a similar check in there if
post_max_size is smaller than
upload_max_filesize. This should also move to the system check.
