Ezigrade 2.7

Have made a number of changes.

1. When deleting links the other fields in the job could get corrupted and you had to redefine all the sections.
2. Trimble (.gps) file was being formed incorrectly for odd lengths eg 1.5m. Even lengths always worked.
3. When importing gps files there is an option to thin the data if necessary.
4. Menu items are more logical.
