Use regular expressions instead of Lua patterns for find and replace editor commands.
Syntax files can now use regex or Lua patterns as before keeping backward compatibility for plugins.
When the number of files in a project directory is above the max
limit switch back to a mechanism to read directory content only
when the corresponding folder is expanded in the treeview.
When the command core:find-file is invoked the command core:open-file
is executed instead because the complete list of the project's
files is not available.
When a project search is done we search through all the files within
the project dir without indexing them.
Address issues #217#203#183.
It make sense to not put the initial '/' in the filename as the name
is relative to the top directory it belongs to.
By removing the the initial '/' in the filename we can re-introduce the
variable
core.project_files
to stay compatible with standard Lite. The project_files variable will
always point to the files table of the first entry of
core.project_directories.
