Improved regex on eventMacro plugin (Runner.pm)

[Nipodemos]

hello again

this pull request now add the possibility to save values you get from regex!!
for example:

$phrase = Name: Nipodemos, Age: 21
if ($phrase =~/Name: (w+)\, Age: (\d+)/ ) {
    log name is: $.lastMatch1
    log age is: $.lastMatch2
}

output:

[eventMacro log] Name is: Nipodemos
[eventMacro log] Age is: 21

this can be VERY helpful in macros, for example when you want to get an specific part of a BusMsg (like coordinates you send)
or when you in your merchant and receives the privMsg asking for an item, you can get the name of item e trigger acoordingly

Also, i've added more comments and changed the name of a few variables, because it was SO HARD trying to find out the logic behind the hole statement process, i hope this helps other people when it goes to change this file 😃
