//This script looks more lika a basic example of how such a system can be implemented. 
//All of it was written in some 5 minutes so some things you might expect may be missing.
//The basic usage is:
//You set this thing up on your server, then you can do the queries that will update the progress of the tasks via http get
//just navigate to http://localhost_or_whatever_your_host_is/tsk.php?set=1&amp;idkey=some_log_string_used_as_id&amp;task=myTask&amp;m=0&amp;M=100&amp;v=10
//The same thing in plain words:
//idkey is a unique string that is used to auth the user. Say you have a whole family using one db for tasks - each member can have a task called myTask. 
//Without knowing the idkey one cannot change or query task status
//task is the name of the task, be creative =)
//m stands for minimum value, In the example this is zero
//M stands for maximum value, In this example 100
//v stands for actual value. 
//Now, once you've set your scripts to update their progress, either with this script or directly to db, time to setup makeProgress plasmoid. 
//Nikita promissed that it will soon be able to fetch the progress via an url by itself, but while it cannot, do the following
//Create a new 'poll' progress and tell it to poll the following app: wget -O - http://localhost_or_whatever_your_host_is/tsk.php?idkey=some_log_string_used_as_id&amp;task=myTask
//That's all and should be self-explanatory.
//To setup the database do the following, apart from uploading this script to your host
//Run this shit in php admin, adjust the name of the table if needed
/*
 CREATE TABLE `tasks` (
`idkey` VARCHAR( 255 ) NOT NULL ,
`task` VARCHAR( 255 ) NOT NULL ,
`min` INT NOT NULL ,
`max` INT NOT NULL ,
`value` INT NOT NULL ,
