SASProcessNote not stored correctly by SaveCanSAS1D

[AntonPiccardoSelg]

Steve reported the following:

I’ve discovered that there is a problem with the structure of the CanSAS1D xml file when you include a Processnote.

At present, SaveCanSAS1D is writing this if there is no Processnote:

       <SASprocess>
            <name>Mantid generated CanSAS1D XML</name>
            <date>08-Jul-2016 11:11:10</date>
            <term name="svn">3.6.0</term>
            <term name="user_file">C:/Masks_16_2/USER_SANS2D_162D_2p4_4m_M4_Festa_12mm_SampleChanger.txt</term>
            <SASprocessnote/>
       </SASprocess>
       <SASnote>
       </SASnote>

And this if there is:

       <SASprocess>
            <name>Mantid generated CanSAS1D XML</name>
            <date>15-Jul-2016 14:14:04</date>
            <term name="svn">3.7.1</term>
            <term name="user_file">C:/Masks_16_2/USER_SANS2D_162D_2p4_4m_M4_Festa_12mm_SampleChanger-MaskFlare.txt</term>
            <SASprocessnote/>
       </SASprocess>
       <SASprocess>

Created: E:/Python Bits/M3_42-added_rear.xml - {(1.0 x E:/Python Bits/D2O-Rome-2nd-MT_rear.xml) + (0.57 x E:/Python Bits/H2O-MT_rear.xml)}

       <SASnote>
       </SASnote>

As you can see, a blank line has crept in above SASnote, but also the Processnote is bounded by SASprocess and note SASprocessnote and is in the wrong place. The correct structure should be:

       <SASprocess>
            <name>Mantid generated CanSAS1D XML</name>
            <date>15-Jul-2016 14:14:04</date>
            <term name="svn">3.7.1</term>
            <term name="user_file">C:/Masks_16_2/USER_SANS2D_162D_2p4_4m_M4_Festa_12mm_SampleChanger-MaskFlare.txt</term>
            <SASprocessnote>

Created: E:/Python Bits/M3_42-added_rear.xml - {(1.0 x E:/Python Bits/D2O-Rome-2nd-MT_rear.xml) + (0.57 x E:/Python Bits/H2O-MT_rear.xml)}

This is why the Processnote was not being rendered by the xsl yesterday. And it stops the files being read back in SasView.
