attempt to fix threading issues when setting conditional breakpoints in GUI * file-editor-tab.h, file-editor-tab.cc (file_editor_tab::dbstop_if, file_editor_tab::request_add_breakpoint): New signals. (file_editor_tab::handle_dbstop_if): New slot. (file_editor_tab::file_editor_tab): Connect dbstop_if signal to handle_dbstop_if slot. Connect request_add_breakpoint to handle_request_add_breakpoint. (file_editor_tab::handle_context_menu_break_condition): Don't attempt to process everything in the GUI thread. Instead, emit dbstop_if signal to get condition and set breakpoint.
