I've finally taken a look at the linear regression plugin. Allowing for 
multiple predictors did not seem too hard to do, and highly useful, so I 
added this for inclusion in 0.4.8.

While at it, I slashed down the .php file for now, by simply printing the 
result with rk.print(), i.e. R2HTML. Since basically we were producing mostly 
the same output, this seemed much easier, and safer for now. Also, previously 
the description of the estimated coefficients was not included in the table, 
and this was the easiest way to fix that. For the future, the code is still 
in SVN, so we can revisit this later, when we want to improve the output 
formatting. Is this ok with you?

Could you please take a look, and do some testing on this?

Regards
Thomas
