(GH-1364) - update template service to generate UTF8 files without BOM.

[Benny1007]

Updated TemplateService.cs to use UTF8Encoding with no BOM when creating the template files in relation to #1364

Not sure why other files were updated, this is my first ever pull request.

@Benny1007 Are you still interested in completing this?

i can't even remember this, is it still required?

[AdmiringWorm]

@Benny1007 IMO, it is still a valid contribution as files are even being generated with BOM.
It looks like the PR would need to be cleaned up, though, and at least the PowerShell files you have changed to not generate with BOM needs to have BOM (otherwise PowerShell will read them as ASCII).

However, PR #2064 perhaps could supersede this one as it is also up to date.

I think we could go for #2064 to supersede this - there were some files in here that did not appear to need to be adjusted that needed to be pulled out. It also doesn't appear that the CLA was signed (CLAHub the older one is showing as not signed, but it could have been at the time this was submitted). Thoughts?

@gep13 This should be able to be closed as #2064 has been merged

@TheCakeIsNaOH makes sense to me. Thanks for pointing this out!
