/* This script adds Contributions and Statistics tabs to User and User talk pages. For Vector skin.

This script was originally written by [[User:Equazcion]] and rewritten mostly from scratch by [[User:HueSatLum]].

To use this script, place the following line in your vector.js page:

	importScript('User:Equazcion/ContribsTabVector.js'); // Backlink: [[User:Equazcion/ContribsTabVector.js]]

Add any or all of these lines after the importScript line above to set various options (the default values are shown):

	var contribsTab = true;                    // Turns the Contributions tab on or off (set to false; for off)
	var contribsTabStats = true;               // Turns the Statistics tab on or off (set to false; for off)
	var contribsTabNumber = 50;                // Number of contributions to display in the Contributions tab. Can be 1 to 5000.
	var contribsTabName = "Contributions";     // Custom name for Contributions tab. Replace quoted text with your desired name.
	var contribsTabStatsName = "Statistics";   // Custom name for Statistics tab. Replace quoted text with your desired name.
