Revert w_crit_cfl back to 1.0 (from temporary 1.2) (#1510)

TYPE: bug fix

KEYWORDS: IEVA, cfl

SOURCE: internal

DESCRIPTION OF CHANGES:
This is a clean-up PR to 4412521 #1373 "Implicit Explicit Vertical Advection (IEVA)". We are resetting the 
default critical value to activate the w_damping option to the previous setting.

Problem:
The new namelist option `w_crit_cfl` replaces `w_beta`, where `w_beta` used to be set in module_model_constants.F and had a value of 1.0. Before this PR, the default value of `w_crit_cfl` was set to 1.2 in the Registry. If one didn't use the new namelist option to manually reset the value of `w_crit_cfl` to 1., that meant that w_damping would behave 
differently from previous releases.

Solution:
1. With consultation with the developer, the value for `w_crit_cfl` is now set to 1.0 in the Registry file. This gives similar and expected behavior for when w_damping kicks in.
2. Also, a bit of column aligning in the neighborhood of this change was done to make the Registry a bit more tidy. "Try and leave this world a little better than you found it.", Robert Stephenson Smyth Baden-Powell.

modified:   Registry/Registry.EM_COMMON

TESTS CONDUCTED: 
1. There are no problems to test, just resetting the critical value for activating w_damping (from 1.2 to 1.0).
2. Let us all hope that Jenkins tests are all PASS.
