Incompatibility with mathastext and XeLaTeX

[michaelroland]

Due to the latest updates to mathastext, the template no longer compiles and fails with

! Extended mathchar used as mathchar (4203026).
<to be read again> 
                   }
l.1241 ...letters\string-\mathbin\mst@varfam@minus
                                                  
A mathchar number must be between 0 and "7FFF.

See eea692c

This can be overcome by providing the deprecated option everymath to the package mathastext.

The option nominus (to not substitute the minus with the text font) also solves this. Maybe use the combination noplus,nominus,noequal to avoid the above error while maintaining style consistency for these three essential operators (+, -, =)?

Issue has been acknowledged by mathastext author via personal e-mail. Proposal was to stick with everymath for now. A fix for mathastext will be provided before removal of the deprecated everymath option.

For now, this is resolved by #14
