Language problems in "Guidelines!"

- First line: "Enthousiasts" --> "_Enthusiasts_"
- 1.: "[...] custom scripting for playermovement?" --> "[...] custom scripting for _player movement_?"
- 4.3.: "Tell us that the error message(s) is, if any." --> "Tell us _what_ the error messages _are_, if any."
- 6.: "We expect you to put effort in your own problem." --> "We expect you to put effort _into_ your own problem."
- 7.: "You won't reach anything with it" --> "You won't _gain_ anything _from_ it."
- Third last paragraph: "[...] some help with his topic, just link this page so he can improve it [...]" --> "[...] some help with _their_ topic, just link this page so _they_ can improve it [...]" (Gender neutral pronouns)
- Opening & Closing paragraphs: Change "I" to "We". "We" is used in the rest of the post as well; also sounds more inclusive/inviting.
