- added raw_prepend / raw_append to vhosts & locations, which
adds raw lines to the vhost/location /without/ semicolons
- added location_raw_prepend / location_raw_append to vhost
for passing through to default location
- added spec tests for new parameters
- cleaned up location specs to match new header/body/footer setup
reducing duplicate checks by testing header/footer separately.
- cleaned up whitespace (2 space) in touched files
- used `<%-` in erb templates to allow the use of leading
whitespace, making the logic flow more readable
- Also adds spec tests for recent vhost updates:
- client_body_timeout
- client_header_timeout
- gzip_types
- testing that the first server_name is used when www_to_non_www is true
