ACTION array allocation too small

[ukmo-ccbunney]

Describe the bug
The ACTION array in the wminitmd.f90 subroutine WMINITNML is allocated with an upper bound of 9:

WW3/model/ftn/wminitmd.ftn

Line 4081 in 482c500

ALLOCATE ( ACTION(JFIRST:9) )

but it is later accessed with array indices > 9 e.g.:

WW3/model/ftn/wminitmd.ftn

Line 4167 in 482c500

ACTION(7:11) = '- '

The WMINIT subroutine also contains an ACTION array, however this is defined as a static array of the correct size 11:

WW3/model/ftn/wminitmd.ftn

Line 429 in 482c500

CHARACTER(LEN=6) :: ACTION(11), YESXX, XXXNO

To Reproduce
Running a multi-grid model using NAMELIST input (ww3_multi.nml) causes a runtime error.
The error does not occur when using ww3_multi.inp (WMINT is called rather than WMINITNML)

Expected behavior
Not segfault when using ww3_multi.nml

@aliabdolali I can put a fix for this bug in PR #372 if you like. Or would you prefer a separate PR for this one?
