new resample printer makes tuneParams printer ugly.

[ja-thomas]

library(devtools)
load_all()
configureMlr(show.info = TRUE)

ps = makeParamSet(
  makeNumericParam("C", lower = 0.01, upper = 0.1)
)

ctrl = makeTuneControlRandom(maxit = 5L)
rdesc = makeResampleDesc("CV", iters = 3L)
measure = acc
discrete_ps = makeParamSet(
  makeDiscreteParam("C", values = c(0.5, 1.0, 1.5, 2.0)),
  makeDiscreteParam("sigma", values = c(0.5, 1.0, 1.5, 2.0))
)
res = tuneParams("classif.ksvm", task = iris.task, resampling = rdesc,
  par.set = discrete_ps, control = ctrl)

[Tune] Started tuning learner classif.ksvm for parameter set:
          Type len Def      Constr Req Tunable Trafo
C     discrete   -   - 0.5,1,1.5,2   -    TRUE     -
sigma discrete   -   - 0.5,1,1.5,2   -    TRUE     -
With control class: TuneControlRandom
Imputation value: 1
[Tune-x] 1: C=2; sigma=0.5
Resampling: cross-validation

[Tune] Result: C=2; sigma=0.5 : mmce.test.mean=0.0533333

And it ignores show.info

Some of the resample output ignores show.info now m(

@larskotthoff
there are mutiple problem with this now. in the merge of the PR you said we should direct abuse your way...

did you check that the PR really works? by running stuff and looking at it?

[berndbischl]

this needs to be fixed ASAP as it breaks mlr core

[larskotthoff]

Fixed in #1974. Please check and merge.
