Changed ls_sniper third person hold type.

Because http://puu.sh/44xgs.jpg looked retarded.

So now you hold it like http://puu.sh/44xhh.jpg
Tidying up: Categorized DarkRP Sweps

A lot of custom SWEP coders neglect to put their weapons into a
category, making the "Other" category very messy on some DarkRP servers.
Especially as Garry has joined the lazy categorization band-wagon.
(Referencing his Medkit, Manhack gun, and fists)

So now Darkrp weapons will appear under the DarkRP (Weapon) category.
Utilities and other non-weaponry such as keys, pocket, lockpick, weapon
checker, etc appear under DarkRP (Utilities). This cleans up a lot of
the "Other" window, allowing admins to better find the weapon they are
searching for to give someone.

I pulled this to master as I didn't consider it to be against the
feature freeze.
Merge pull request #938 from Redfiend/master

Minor SWEP changes
