Synx manpage and source wrt option capitalization

We had a spelling discrepancy between the manpage and the source code
for some option. Resolve these in favor of the manpage, because it
makes more sense (for example, HTTP should be capitalized).

changes/HTTP

+  o Code simplifications and refactoring:
+    - Some options used different conventions for uppercasing of acronyms
+      when comparing manpage and source. Fix those in favor of the
+      manpage, as it makes sense to capitalize acronyms.
