Need the ability to parse saved data by regex

[danvideo]

When WebMinion runs and performs the :save_value method, it will likely return extraneous text as well desired text.

For example, say you want a particular table element and "target" : "//td[1]" there will probably be extra text there, such as this:
#<Nokogiri::XML::Element:0x3fe5fcc42a58 name="td" children=[#<Nokogiri::XML::Text:0x3fe5fcc47468 "SPECIFIC TEXT AND ID HERE: ">, #<Nokogiri::XML::Element:0x3fe5fcc46e00 name="i" children=[#<Nokogiri::XML::Text:0x3fe5fcc46810

So a generic bot method - irrespective of bot driver - to run a regex on saved_data values to clean up data would be great.

One possible way to go about this is to add a few more attributes for save_value, e.g.

{
  "name": "Save Price",
  "target": "#item_price",
  "value": "prie",
   "type": "integer",
   "is_validator": false
}

Where type can be one of the following: text, integer, number, regex.

Thoughts?
