ispman-HEAD tasks cleanup

Hi all,

Short summary,

After some time, I have got the chance to work again on ISPMan.
I am helping Joerg to do the cleanup so the code is easier and the logic 
is not everywhere.

2 main changes I did recently are.

1. params are passed by name to processes.
    Until now we were passing a comma separated list of items and the 
recieving function knew how to process it. This starts to get ugly... so 
we change to name=value&name=value style as in GET URLs.
For example: here are the params passed to process createHomeDirectory
uid=xx_test_com&homeDirectory=/ispman/domains/test.com/users/xx_test_com&uidNumber=2279&gidNumber=2235

This way the function can recieve the parameters as a hashref and things 
get easier....

2. All the processes were defined in ispman-agent. This started to get 
hairy too, there was pieces of logic every where.
Now we have removed all the processing functions from ispman agent and 
put them in a task directory.

In this directory you will find tasks that ISPMan writes to the 
processtable. These tasks have almost no logic. They are just like a 
batch script.

The task execute one or more commands with parameters. The commands can 
be system commands such as rm, cp etc or ispman.* commands.

It gets easier to understand what happens behind a task.

please let me know your comments.

best regards
