as currently there is no other ui to indicate that other formats besides .ifc are supported and I guess we just expect users to change extension in the saved filename

when the user ran the web ui for the first time. the running_pid file was not created yet by the server so it threw an exception due to with open not inside the try block
This change affects the following recipes: `OffsetObjectPlacements`, `OffsetStoreyElevations`, `SetFalseOrigin`, `SetRefElevation` and `SetWorldCoordinateSystem`
remove_style relies on style_type which is using StylesData to get the enum of it's values and StylesData will fail to load on `material = tool.Ifc.get_object(ifc_file.by_id(style.ifc_definition_id))` as ifc_definition_id was removed but not yet removed as an item from styles ui.
This issue doesn't occur when user is working from UI since StylesData precached when they load styles UI but if they run a script (as we do in bim tests) StylesData is not precached and will be loaded when get_active_style_type() is called leading to errors.
1) As adding new styles means it's not assigned anywhere, there is no need to keep graph up to date.
2) Removed Ifc Operator super class from couple operators that do not write ifc data
3) Moved common code to tool.Style
To easier create and display properties that allow one or more files as input, a `MultipleFileSelect` property group has been extracted, together with an operator for selecting the files and the code for displaying the property.
