Correct clicking data point for info

closes #134 (closed) #86 (closed)

• Modify function get_index_from_time into get_index_from_data_picked to be simpler and handle wrong index detect in upDownDots type.
• Retrieve data from plotting_data2 for detecting mass position info.
• Fix bug that call combine_data() for RT130's soh_data which remove logIdx from data. This bug causes clicking on point cannot connect with search_message_dialog.
