moved to htmlelements

still test fails with nullpointerexception
still for the same problem - can't create proxy, but now - even for
predefined elements of htmlelements framework
something works:)
added more files
added checking that listed products are displayed

  - more static content tests:
    - check products:
      - displayed
changed from loginBtn.getWrappedElement to loginBtn.isDisplayed() in isLoaded()

this also corresponds to all other pages.
ther reason is that proxy is acually a wrapped element inside
typifiedelement, and not the latter… So to check that proxy work, we
need to call any method of wrapped element, not a typified element:)
added test to check all listed products for a user, admin

dataproviders are still not DRY
also it would be great to check "empty" products for user with no
products assigned or for admin with a clean database of products
populated pagesWithProductNamesList dataprovider with poor user (having no products)

in the future when we will setup the configuration for pine database
for each test we also need to add a test for "poor admin"
added support for @DataProviderArguments, not tested though. Before big changes:) in dataproviders:)
added DataProvider template to use string args for it; moved all 'staticContent' dataproviders to a base 'staticContent' class
merged yaf to pinetest: yaf is now the 'core' inside pinetest
updated worklog.yml
