Incorporate small changes to outputs in fm.tpl in Ingrid and Carey's versions

[careymcg]

Ingrid and Carey have both added things like sample size to the fm.tpl outputs but these changes are not in the main branch of the repo.

Also, change hardwired line in writing out Tier 3 projections to get rid of hardwired spawnmo =2 and some other hardwired outputs there (like number of sexes, number of fisheries, maxage, etc.):

projmod <<"0 # SSL Species???         " <<endl;

	double mean5yrF=0.;
	for (int iyr=endyr-5;iyr<=endyr;iyr++) 
	  mean5yrF += max(value(F_f(1,iyr)));  mean5yrF/=5.;
