[ic] Permit more places in price field

[interchange-users@icdevgroup.org (Geoff Sternecker)]

Using the foundation templates with no sample data,
I'm adding a variant for a matrix option, that has 8 values each changing
the price.
So, I want to add to the Price field
A=100, B=200, C=300 ... H=800,

The field seems to be limited to about 20 characters, where can I change
this?
Is it set in the MySQL Database, or can I change a template in Interchange?

I'm adding 8 more variants, so going through and changing all possible
combinations by hand, isn't my first choice.

Thanks in advance,
Geoff Sternecker
