Manage ampersand in Windows install path in TXM.bat launch script

Under Windows, some users can have an ampersand character (&) in their login names. Example : 'Laura&'.

The consequence is those ampersands break TXM batch scripts if not neutralised.

Ampersands can be in the :

• A) install directory
• B) user home directory

Solution

A) Remove the installdir variable in TXM.bat and do cd /d "%~dp0" at the very beginning

B) wip -> later
