Build 3.0.0.60 of xlsgen is a fix pack.

It includes the following :

- fix for reading the VML anchor associated to comments in XLSX files. Sometimes we would read the wrong one if there is more than VML anchor in the VML drawings so the comment would be located in a wrong place in the sheet.
- better reading of rich formatting in cells overall, particularly when formatting is cancelled rather than set (i.e. bold is removed from the default font rather than bold is set).
- read and render rich formatting strings in XLSX files. These are strings made of more than one font formatting in cells, and they are produced by third-party Excel libraries.
- read rich formatting strings in comments in XLSX files. Support for reading rich formatting strings in comments in XLS files was already supported.
- read rich formatting strings in chart elements (title, axis titles, data labels) from XLS and XLSX files.
- preserve multi-line rich formatting strings everywhere (comments, chart elements, text boxes, vector shapes)
- fix for the "linked to source" flag in chart axis (X,Y, ...). "Linked to source" is a checkbox in the Number format tab which allows to automatically infer the data type rather than having it set custom.
- support for undocumented fonts in XLSX files such as "+mn-lt" (minor latin)
