CFBM: Refinements in the level set

[pedro-jm]

TYPE: bug fix

KEYWORDS: CFBM, fire propagation, default settings

SOURCE: Pedro A. Jimenez (NCAR)

DESCRIPTION OF CHANGES:
Problem:
There are instabilities in the methods used to determine the fire propagation

Solution:

1. We updated the default value of a namelist variable, the pseudo time step coefficient for the level set reinitialization
2. We use the previous ENO method to solve the level set equation

ISSUE: N/A

LIST OF MODIFIED FILES: We only updated the hash of the fire_behavior git submodule

TESTS CONDUCTED:

1. Do mods fix problem? How can that be demonstrated, and was that test conducted?
2. Are the Jenkins tests all passing?

RELEASE NOTE: Refined methods for the fire propagation in the CFBM

This PR seems to have failed the tests. @weiwangncar can you check?

[weiwangncar]

@dudhia I did not receive any test results. I started a re-test and see if it goes anywhere.
