v1.2.0

• Support updating a single common AssemblyInfo.cs #227 thanks @hmemcpy

Note we do not have the assembly info switches in the command line help at the moment, see #237

Usage for updating assembly info is /updateAssemblyInfo if you want to specify the file it is /updateassemblyinfo ..\src\CommonAssemblyInfo.cs or /updateassemblyinfo "C:\src\CommonAssemblyInfo.cs"
