non_numeric value warning when $plugin['flags'] missing

[jools-r]

If a plugin in the plugin cache directory does not contain the flags item or lacks a plugin header at all, ied_plugin_composer outputs the following warning:

Warning "A non-numeric value encountered"
in /path/to/ied_plugin_composer_v1.3.0.php at line 905

This is line 905. It's not really ied_plugin_composer's problem, rather a problem with the respective plugin, but perhaps it can be silenced with this small addition:

$plugpref = ((is_numeric($plugin['flags']) & PLUGIN_HAS_PREFS)) ? ' '.$this->anchor('plugin_prefs.'.urlencode($plugin['name']), '', ' ['.gTxt('plugin_prefs').']') : '';

I'm not sure if that has other implications?

I actually dislike that these flags are defined in the plugin template itself. They should be core, surely? Can't see any reason not to include them as core constants.

But yes, Plugin Composer should handle this better, thanks for the report.
