As asked in pull request ndlibersa/resources#50 , here's a new pull request featuring only the tax fields:

Add new fields to the enhanced acquisitions mode:
    Price Tax Excluded
    Tax Rate
    Price Tax Included

Price Tax Included and Payment Amount will be automatically prefilled accoring
to the Price Tax Excluded and Tax Rate values.

This pull req seems to include the code from pull req #2 (Session Abstraction). @PaulPoulain was this an accident, or did you intend for #2 to be merged first?

I'm closing this request and reopening it as a new PR. Github is registering 14 new commits and intractable merge conflicts when there should only be 3 commits. The other 11 commits contain code that has already been merged into master. A new PR based on the current master branch will resolve this.

Sorry, at least 7 of these are unrelated and mine. :-(
I did a typo in the message of one commit (referencing #3 instead of #36).
And after doing various rebases to fix some errors and sync with master, that duplicated the said commit...
