reloading iOS provisioning profiles etc

[Ben Rubinstein]

After adding a new device to my registered set in my Apple developer account, 
how can I get LC to recognise it?

I go through this every now and then, conduct a lot of superstitious rituals, 
eventually I get there.. but I never know how.

I've launched Xcode, used it to build an app to the device, which caused it to 
say that there was a problem and offer to fix it. Now Xcode can build to the 
new device, but LiveCode still not.

The message (when I ask Xcode to add the newly built app to the device) is

	The executable was signed with invalid entitlements.

	The entitlements specified in your application’s Code Signing
  	Entitlements file do not match those specified in your
	provisioning profile. (0xE8008016).


In LC, I've selected a different provisioning profile, selected the original 
one again, quit and restarted LC, turned to face east, hailed cthulhu, etc... 
all the usual things... still no luck.

So, how do I force LC to refresh the provisioning profiles, or otherwise to 
build an app which can be installed on a new device?

Secondary question: how do I get LC to stop seeing every old profile I've ever 
had (many with the same name) in the "Profile" popup on the iOS tab of the 
Standalone Settings window?

TIA,

Ben
