Pherliac Pod improvment

[Raileks]

For the amount of trouble it takes to get them, I find it bad game design to have such a limited use for this kind of item. I propose giving them a use outside of the Atlas quest as a farming tool.

Change it so that instead of a 10 sec time span it has hp(3000?) and can survive as long as the tenno can keep it from being destroyed(defense mission esque). For every second it last increase the spawn rate and power of the levels infested.  Could also include an item like this for every faction.
