em_les namelist e_vert now consistent across domains (#2274)

TYPE: text only

KEYWORDS: em_les, e_vert, namelist.input, default

SOURCE: internal

DESCRIPTION OF CHANGES:
Problem:
The default namelist.input file in the em_les case directory had e_vert
set to 40, 100, 41, which may confuse beginner users. If they leave
as-is when running a nested simulation, they will get an ideal.exe error

Solution:
Changed the setting to "e_vert = 40, 40, 40."

LIST OF MODIFIED FILES: 
M    test/em_les/namelist.input

TESTS CONDUCTED:
