UsesOfSymbolAtPoint use of ActWin is now configurable with a
myriad of Options (some 100 Options) covering definition of commands
(mapping, command and abbreviations) controlling Scala and ActWin
navigation; Options for how information is displayed in the Scala
and ActWin windows and Options for highlights and signs.
Now, by default, the "uses_of_symbol_at_point" uses the ActWin.
For all available Options, see the newly added PROPERTIES file.
Four new Option "kind"s have been defined supporting Option String
types specialized for "commands", "highlight" definitions,
highlight "group" names and "highlight" or "group" name.
As examples (see PROPERTIES file), the (current) default value
of 'tailor-actwin-display-actwin-cursor-line-highlight' is
"cterm=bold ctermfg=DarkYellow ctermbg=Cyan" and the (current)
default value of 'tailor-actwin-display-scala-color-line-kinds-marker-linehl'
is "Search" (a highlight group name).
In the future, rather than using the existing options_project.vim
and options_user.vim files, Options will be able to be set
using a (standard Java format) properties file. While some code
to do this has been checkin, it has not been extensively tested.
