Basic detection for MS Word's internal link checker. This is not perfect,
as older versions use IE6/7 user agent string with no identifying marks,
and newer versions don't necessarily identify themselves as Word (just as
Office). Version information is not reliably available, even when there
is sufficient other information to identify it as Word's link checker.
This is also based on a small sample of Word / OS version pairings, so
there may be some which are identifiable but not currently covered.
* core_useragent: Introduce is_vendor methods to improve readability
when we are just detecting if a browser is from a vendor, rather than
the exact version
* Remove uncessary browser version checks when we are just detecting
vendors - this makes the intention of our sniffing clearer.
* Remove sniffing for browsers which we do not support, grades/ajax/tinymce
all support modern browsers so there is no need to sniff for them.
This commit moves user agent related functionality out of several
core libraries and combines it into a more manageable class.
All core uses are converted and functions deprecated in favor
of the new class.
