update timestamp for LoC ISBN retrieval
add MEDLINE/nbib import translator
this should work better for authors with ISI - doesn't rely on space at beginning of line
add import translator for OVID's tagged format (as exported to Endnote, Citavi et al). This is a _terrible_ data format and there is a lot of guessing and regex cleaning going on, but that's the best we have. I'll eventually switch the OVID web translator over to this, as it's much better than the scraping (of the same format) included there.
fix a couple of OVID Tagged nits per @aurimasv

[Copernicus] Add AMT/AMTD to target list
fix SCOPUS after site redesign
[RDF] Fix for dc:type = 1 (or some other integer)
Did not bump Embedded Metadata timestamp on purpose
fix Pion Journals for an alternate display. We could look into using the RIS in the medium run, that'd be much cleaner.
[ISI] Add some temporary debug code
implement month xregex for Ovid Tagged month parsing, thanks to @aurimasv for the pointer
I decided to not parse days, they're rarely needed
Bibtex import translator is now called instead and other imrovements

* Bibtex import translator is now called internally (this deals with all kind of character encoding problems as well as spacing problems)
* every entry types is handled now by just checking if the class "entry" is contained in the list of all classes
* detectWeb is (for creating the right symbols) updated
* there are also person-pages, i.e. lists of publication from an author (added in detectWeb as multiple)
* cases where DBLP uses crossref fields and links for example an inproceeding to the proceeding (second entry) is dealt and the information of it is used as well
* replace BibTeX field "ee" (DBLP) which is normally named "url"
* some fixes and code improvements according to the comments by aurimasv and adam3smith
* asynchronity with import calls are handled: import on second data (if any) is called before the import on first data, such that the additional information from the second data item can be added in the corresponding fields with the first data
* url with doi are handeled better
* Improving code and test cases

turn contributors into editors for MARC (see e.g. https://forums.zotero.org/discussion/34653/editors-of-books-not-downloading-correctly-with-iiimillennium-catalog-translator/#Item_3 we're already doing this in some library catlog translators, no reason not to unify that)

[biblatex] Extended language support and several small enhancements

- (Almost) All babel languages can now be written to langid.
- Add getCollections : true for exporting collections recursively.
- Default to type = phdthesis if type field for a thesis is empty or contains "PhD" in any reasonable form.
- Handle special cases of bookSection -> inbook (for parts of a book which isn't a collection, i.e. has bookAuthor) and book -> collection (for books without authors but with editors).
- Some deprecated code was fixed
