Simba now has some parameters (-o/--open to open a file and -r/--run to run that file at startup). Simba now opens a file correctly if you double click an associated .simb file. Initalized several TPA-functions-results.. (BoxFromTPA could return random values when sending an empty TPA). Opening/Creating a 'script' will now happen in a new tab (unless the current tab is the same as the default script) Restructured the internets unit (+ implemented all of the HTTP-client stuff). And updated the Synapse units. git-svn-id: http://www.villavu.com/repositories/merlijn/mufasa@538 3f818213-9676-44b0-a9b4-5e4c4e03d09d
