ARC2_RemoteStore::runQuery() decides when to use GET or POST.

[WiredAcademic]

Currently $mthd is used to decide both the Method and whether reading or writing is occurring. This should probably be separated. Then, it might be better if a variable could be set to override this behavior (or config option).

The reason I bring this up, is my hosting services restricts the query string value lengths by default to 512, and my SPARQL queries were running ~800 in length. I'm fixing my account, but it got me thinking... maybe it would be better to have a config option for using GET or POST.

Also, the current implementation uses the "$mthd" (method) to decide whether to use 'store_read_key" or "store_write_key". Instead, a variable called "$is_read_operation" could be used.
