first run of in-place templatization with gomplate

[erharb]

Not quite successful run using gomplate in-place.

Desired

• Files with ".tmpl" extension renamed, overwriting files of that new name where present (e.g. README.md.tmpl in place of README.md).
• Folders/file names with substitution values in them should be removed (e.g. /packaging/{{{{.data.Name}}}})
• Folders/files found in .gomplateignore should be removed.
  • Note that .git folder needs to stick around also, but removal of it from .gomplateignore may have caused git index errors...

Actual

• Files with ".tmpl" extension were not renamed where file of new name are present.
• Folders/file names with substitution values in them are kept alongside their renamed counterparts.
• Folders/files found in .gomplateignore are kept alongside templatized folders/files.
