Allow InChI paste support from e-EROS

Correctly-formatted standard InChI strings start with "InChI=1S/". However, the web database e-EROS formats them as "InChI = 1S/", with spaces around the = sign. Although this is incorrect, it could be nice if ChemDraw allowed pasting directly from e-EROS for the Edit > Paste Special > InChI feature by allowing spaces to either be present or not present. The strings are accurate other than these two spaces per string.
