Renamed file with typo in the filename

Hello, i have a trouble with typo in the file name PlatformUiFilters.groovy, so i added some changes. I looked at jira and i know that it is the bug with max priority. I don't know, if you still develops platform ui, but i think, it is very convenient and useful thing. 
And i want to know, if you will continue to develop platform ui (we want to use it in a project). 
Excuse my bad English! And Happy new year!
