PowerTOST v1.4-1

• Objects of class 'regSet' now have an additional component 'est_method'
  which controls the simualtions via key statistics of the evaluation using
  EMA's ANOVA or FDA's recommended ISC.
• power.scABEL()/power.scABEL2() as well as sampleN.scABEL()/sampleN.scABEL2()
  are now unified. The regulator component 'est_method' is used for switching
  between sims based on EMA's ANOVA evaluation or ISC evaluation, respectively.
• power.scABEL2()/sampleN.scABEL2() are therefore deprecated and will be
  removed in future versions. A corresponding warning is thrown.
• URL of PowerTOST on GitHub added, URL for bug reports added.
