some spelling and minor grammatical errors

[vomikan]

In the section About Reports there is a sentence that begins "With out internal templating engine" which is grammatically incorrect as "Without a internal templating engine" is obviously what was intended. And at the end of the this very sentence there is a phrase "LUA codes, and front-end scripts" which seems to be not quite right, "LUA coding", "LUA programming", "LUA scripts", or "LUA scripting", or simply "LUA" seem to be more grammatically correct to my ear than "LUA codes".
