…ts after each instruction execution

Two new parameters can be given on the command line to see what fitnesse is currently doing
1)
A) slim.sbys=SHOWTABLE
show the html table after each executed instruction
B) slim.sbys=SHOWINSTRUCTIONS
show the instruction after each executed instruction
C) slim.sbys=TRUE
instead of sending a full tabke to the slim client send just one instruction each time
2) only if 1 is given, will delay the execution by 0.5 seconds just useful for showing the beaviour
slim.sbys.sleep=SLEEP

Examples:
http://localhost/FitNesse.SuiteAcceptanceTests.SuiteSlimTests.TestComparators?test&slim.sbys=SHOWINSTRUCTIONS&slim.sbys.sleep=SLEEP
http://localhost/FitNesse.SuiteAcceptanceTests.SuiteSlimTests.TestComparators?test&slim.sbys=SHOWTABLE&slim.sbys.sleep=SLEEP

…e slim.sbys =SHOWINSTRUCTIONS

Added documentation
all code for the display is now in the SuiteHtmlFormatter and not in the SlimTestSystem

Removed the limitation that the instructions are only show after the execution.
Now they are first shown with as "in progress" and after execution the actual result is added.
