Need access to mapResource like we can mission via a function like 'getValueDictByKey'

[TEMPEST.114]

env.mission has the following:

 

pictureFileNameN
pictureFileNameB
pictureFileNameR

 

However it's impossible to get the 'actual' file name - instead all we can get is the obfuscated 'ResKey' for it. 

There is no equivalent 'getValueByKey' for objects in the mapResource file.
