Support order for targets

[khalidchawtany]

When showing alternatives for a file I prefer some more frequent used ones to be shown first. Using this PR the config can be done in the following ways:

{
    pattern = "(.*)/models/(.*).php",
    targets = {
        { template = "[1]/models/[2].php",                      label="Model",        enable_new = true , order=1 },
        { template = "[1]/controllers/[2:pluralize].php",       label="Controller",   enable_new = true , order=2},
        { template = "[1]/models/[2:lower]/*fields.yaml",       label="Fields",       enable_new = true , order=3},
        { template = "[1]/models/[2:lower]/*columns.yaml",      label="Columns",      enable_new = true , order=4},
        { template = "[1]/models/[2:lower]/*.*",                label="Model-F",      enable_new = true , order=5},
        { template = "[1]/controllers/[2:pluralize,lower]/*.*", label="Controller-F", enable_new = true , order=6},
    },
},

or non-verbose method:

{
    "(.*)/controllers/(.*).php",
    {
        { "[1]/models/[2:singularize].php",                       "Model",         true, 1},
        { "[1]/controllers/[2:pluralize].php",                    "Controller",    true, 2},
        { "[1]/models/[2:singularize,lower]/_config_form.yaml",   "Config Form",   true, 3},
        { "[1]/models/[2:singularize,lower]/_config_list.yaml",   "Config List",   true, 4},
        { "[1]/models/[2:singularize,lower]/_config_filter.yaml", "Config Filter", true, 5},
        { "[1]/controllers/[2:pluralize,lower]/*.*",              "Controller-F",  true, 6},
        { "[1]/models/[2:singularize,lower]/*.*",                 "Model-F",       true, 7},
    },
},
