Added launch configurations to git
reworked some mouseover code, mouse listeners are added in one spot now, and removed unneccessary variables
tooltip texts set to null instead of empty string, to avoid random dots
input file title displayed as part of graph title, when opening a file (either savefile or drag-n-drop)
vsrti graph title will return to normal when data is deleted
added actionlistener to VSRTI fields, so pressing enter works as expected
