Fix incorrect max upload file size on forums

The file size is calculated and displayed as a number of bytes, but was
being incorrectly labeled as 'K' [0].

The size is now correctly labeled as "bytes" and the sentence now begins
with a leading captial letter.

Impact: This has been broken on master since 2012 [1].
