Syntax via argument enhanced

The argument, which was so far treated as either number of items or number of days (when negative), can now also be a date. A date must be in the format yyyymmdd (like 20200223) for being recognized as such.

Major refurbishment

• The -match option got removed.

• Any character vector passed as argument is now treated either as a namespace path (when it starts with
  either a # character or a ⎕ character) or as a path to be investigated.

• ]Latest is now capable of dealing with multiple open acre projects: in such a case the user is prompted.

• When there is no open acre project, acre is not required anymore for ]Latest to work.

• When there is no open acre project but the current directory points to an acre-managed project, you
  might consider specifying APLSource as argument now.

• The option -all was added. By default only APL source file are considered by ]Latest. Such files are
  identified by their extension. For which extensions are supported see
  https://github.com/the-carlisle-group/Acre-Desktop/wiki/Item-types-and-File-types

  In addition the file types .dyalog and .dyapp are supported as well.

  If you want all files to be considered then you need to specify the -all flag.

• The option -recursive= was added. It defaults to 1, but you might set it to 0.
