Summary:
Various commands are missing their description in the Help section, because the description is missing from the .lang game file. These include:

• clear
• effect
• me
• playsound
• replaceitem
• setmaxplayers
• spreadplayers
• stopsound
• testfor

Steps to Reproduce (example):

1. Type '/help me' in chat (or use any from the list above)

Observed Results:
A generic reference to where the description should be is shown on screen.

Expected Results:
I expected to see the description printed on screen.
(For a working example, use '/help kill')

Screenshots/Videos attached: Yes

Notes:
See this comment for the missing sections of the .lang file that can be added.

Original Description:

When typing '/help effect' or '/help me' there's no description for the command.
