Move docs on the build API out of 'misc' and under 'Images' section

It seems odd to have such an important API hidden under 'misc'.
While in there I noticed that during the "-f Dockerfile" PR I changed
the query param from f to dockerfile and missed this one spot in the docs.

+`POST /build`
+
+Build an image from a Dockerfile
+
+**Example request**:
+
+        POST /build HTTP/1.1
+
+        {{ TAR STREAM }}
+
+**Example response**:
+
+        HTTP/1.1 200 OK
+        Content-Type: application/json

+        {"stream": "Step 1..."}
+        {"stream": "..."}
+        {"error": "Error...", "errorDetail": {"code": 123, "message": "Error..."}}
+
+The input stream must be a tar archive compressed with one of the
+following algorithms: identity (no compression), gzip, bzip2, xz.
+
+The archive must include a build instructions file, typically called
+`Dockerfile` at the root of the archive. The `dockerfile` parameter may be
+used to specify a different build instructions file by having its value be
+the path to the alternate build instructions file to use.
+
+The archive may include any number of other files,
+which will be accessible in the build context (See the [*ADD build
+command*](/reference/builder/#dockerbuilder)).
+
+Query Parameters:
+
+-   **dockerfile** - path within the build context to the Dockerfile
+-   **t** – repository name (and optionally a tag) to be applied to
+        the resulting image in case of success
+-   **q** – suppress verbose build output
+-   **nocache** – do not use the cache when building the image
+-   **pull** - attempt to pull the image even if an older image exists locally
+-   **rm** - remove intermediate containers after a successful build (default behavior)
+-   **forcerm** - always remove intermediate containers (includes rm)
+
+    Request Headers:
+
+-   **Content-type** – should be set to `"application/tar"`.
+-   **X-Registry-Config** – base64-encoded ConfigFile objec
+
+Status Codes:
+
+-   **200** – no error
+-   **500** – server error
