issue-#44 unicode content of links&targets saving wrong way

[Josef Templ]

I have now looked more closely into the implementation and have
committed my proposal for the changes into issue-#44.

- elimination of version 0 reverted
- comment for version history added to Link:Externalize
- speed up of HasWideChars by common subexpression elimination
- Strings.Find avoided in Link:Externalize for version = 2
- small refactorings for reducing the amount of version specific code
- change list in chronological order as usual

I think the changes are in a good shape now. I have tested them with a number
of different test cases and found no problems so far.

Please have a look at the diffs at http://redmine.blackboxframework.org/pr ... 997bb3e11b.
