Add option to specify entitlements and allow script to autodetect them

For non-trivial project setup with more than 1 target, there's also more than 1 entitlements file
For example, MyAppProd.entitlements and MyAppTest.Entitlements
The default implementation of  will find _first_ matchint file, which is not the one really needed
In my case I had it picking up Test entitlements while I was resigning Prod target.

Second change is related to passing argumetns to resigh.sh script
We should not use find_entitlements at all
The script has support for reading entitlements from provisioning profile and usign them
As a matter a fact, that's quite a common setup, developers would put keychain group, APN and some other things, but not
the :application-identifier or :com.apple.developer.team-identifier
Those are normally missing in Code Signign Entitlements, but present in provisioning profile
It's a common thing and is covered here: https://developer.apple.com/library/ios/technotes/tn2319/_index.html
