Add projection parameter constraints to UI #186

We have a list of valid ranges and datatypes supplied by science which should 
be applied to the placeholders on the bulk ordering site and enforced in the 
validation for page submission.

Per Science... here are the limits to be imposed:

Re: David's question about setting limits on the projections in ESPA, here are 
the limits we should use: 

UTM zone: 1 to 60

Sinusoidal false easting: Infinite
Sinusoidal prime meridian: -180 to 180

Albers latitude of origin: -90 to 90
Albers central meridian: -180 to 180
Albers 1st std. parallel: -90 to 90
Albers 2nd std. parallel: -90 to 90
Albers false easting: Infinite
Albers false northing: Infinite

Polar Stereographic: Stereographic can be applied anywhere in the globe. Polar 
Stereo uses parameters that center it at or near one of the poles. 
If you want to set limits: If your origin lat/long are fixed based upon scene 
location, then you should make it so 60 to 90/-60 to -90 are your limits based 
upon the scene's location. You'd also have to block any mid-latitude scenes 
from being re-projected into PS. 
If you don't want to set limits: Just allow -90 to 90 for latitude and -180 to 
180 for longitude.
