CMailFile - findHtmlImagesIsSrcData fails - dol_is_dir is not defined

Bug

I have a trigger that create an instance of CMailFile. The trigger is for TICKET_CREATE. This appears to happen when the trigger occurs during an API call to create a ticket.

I was able to get past the bug by adding the following lines in the 'CMailFile::findHtmlImagesIsSrcData' function BEFORE it attempts to call 'dol_is_dir'.

if (! function_exists('dol_is_dir')) {
    require_once DOL_DOCUMENT_ROOT.'/core/lib/files.lib.php';
}

Dolibarr Version

It seems odd that the "htdocs/core/lib/functions.lib.php" uses function from "files.lib.php" but does not appear to include/require the library at the top of the file.
