Using the wrong format for Web.Selenium.WaitTimeout does not cause a meaningful error message to be displayed

[Stephane Mikaty (eCircle AG)]

Reproduction:

1. Set Web.Selenium.WaitTimeout=10000 when calling testplan in Selenium
2. Error displayed

java.lang.RuntimeException: testplan.util.TestPlanException$Syntax: Cannot convert context item
 at testplan.auto.selenium.AutoSelenium.getTimeout(AutoSelenium.java:363)
 at testplan.auto.selenium.AutoSelenium$AutoCommandProcessor.doCommand(AutoSelenium.java:1361)
 at com.thoughtworks.selenium.DefaultSelenium.open(DefaultSelenium.java:335)
 at testplan.auto.selenium.AutoSelenium.open(AutoSelenium.java:439)
(ERROR)

Expected result:
Cannot convert context item %Web.Selenium.WaitTimeout% from 10000 to durationType

Or something like that, you get the idea.
