Old LoadXXX (LoadEventPreNexus, LoadAscii) need "previous versions" documentation and/or deprecation

[Federico M Pouzols]

Checking old versions of LoadXXX (in #8175) this is what I found. For the following algorithm there is an older version that is still in use and documented:

• LoadMuonNexus (v1), see ​http://docs.mantidproject.org/nightly/algorithms/LoadMuonNexus-v2.html#previous-versions

Perfect, nothing to do there. But for the following two algorithms there is no "previous versions" documentation (or about why the older versions are still there):

• LoadAscii (there's v1 and v2 but no information about previous versions in v2's doc: ​http://docs.mantidproject.org/nightly/algorithms/LoadAscii-v2.html)
• LoadEventPreNexus (same as LoadAscii, see: ​http://docs.mantidproject.org/nightly/algorithms/LoadEventPreNexus-v2.html)

For these two, it should be documented why the older versions are still provided (or they should be deprecated if there's no reason any longer). At first glance, in both algorithms, it looks like the newer versions are just expanded versions of the old ones.

Try to find those who might know the history of versions and clarify what's the current status of these algorithms/versions.
