[data-original-title] is used to store original title parameter, as after initializing tooltips BS takes control over title parameter and I want to have reliable way of retrieving og value ("If you want something done right, do it yourself")

initializeTooltip method is almost the same code as before (minus disposing tooltip instance) just moved to new function

hasEllipsisStyle checks for ellipsis style - if there's no such style, tooltip should be always visible. Otherwise, it should be visible only when ... is on screen
hasNewTitle tracks if title was changed by dev - as BS removes completely this value, if it's there at next parsing, it means dev wants to change it.
tooltipInitialized checks if given node was already parsed and is ready to show tooltip

When node has no ellipsis styles we ALWAYS want to show tooltip, so in general after first parse() we don't have to touch it again, except when title has changed (disposing and initializng is necessary to update tooltip content)
When node has ellipsis styles we have cases:

1. name has changed - therefore width could change, we calculate if it should be visible now and init/reinit/dispose it
2. name has not changed; width has changed - we calculate if it should be visible now and init/dispose it

We ALWAYS remove title, as when element has ellipsis styles, has title, but shouldn't have tooltip (no ... visible) there should be no native title/tooltip as well.
