Automatic substituations of tags for repetitions

Currently translate5s repetition auto-adjustment builds on a pure string-comparison of the repeated segments.

If there are tags inside of the segment, this does not lead to repetitions, even if the tags stand for the same characters in the original document due to the need for ids.

This issue will enable translate5 to find every segment as repetition, that has tags in the same places as the current segment - even if the tags represent completely different tags (and even, if in the current segment the tag is an opening tag and in the repetition in the same position you find a closing tag or a placeholder-tag).

The following table shows such a case, where the text in the source is identical, tags are in the same positions, but the type of the tags is different:

translate5 will always ensure, that

• the order of the tags in the adjusted target of the repetition are the same as in the target of repetition before autoadjustment
• that the tags in the "adjusted target of the repetition" are copied from the "target of repetition before autoadjustment" (and not from the source or from the "target as changed by user in translate5")

To ensure, that nothing goes wrong, in one slightly changed case the previous example will not be treated as an example:

In this example one tag in the "target of the repetition is missing. Since translate5 can not know, which tag is missing (at least not without taking the tags from the source instead of the target) in this case no autoadjustment is done.
