New gauges for Avhistory's bf 109E and bf 110C

[bzhyoyo]

Hi all,

this set of gauges is for Avhistory's 3gr_Bf_109e-1_e-3, 3gr_Bf_109e-1, 3gr_bf_110c_4B and 3gr_bf_110c_3

The installation is pretty straighforward and there is some hexediting involved if you want to use all the goodies so I didn't choose to create a self-installer for these. Just read the readme and everything will be fine. If you don't and come asking for something mentioned my answer will be "readme"
