Allow non 'a-z' characters in output headers

Just want to add another example of this: I brought in the Unified Scorecard Fact - company object, and cannot save because the object name (standard object) contains a hyphen and the output header cannot. It should support hyphens and some degree of special characters on top of numbers.

Another one: if I bring in the field “User”, that exists as such, why would I get an error message that the name “user” is reserved and I can’t use it. There needs to be a mechanism to auto-update the names in these instances or just, working around the fact the name is reserved (why is it, because there is no lookup to modified by/created by automatically added to a DD). 

This has peaked now that I’ve had to label my field:

One - EXP(- (N_in_W / tau_const)

Instead of just what it does, aka: subtract EXP(- (N_in_W / tau_const) from 1, so:

1 - EXP(- (N_in_W / tau_const). 

(And yes, with this kind of build, I prefer the field name to be a description of the formula so when I have to add half a dozen transforms because functions can’t be nested in numeric expressions in one step, my formula still looks like the complete calculation).
