Forge anti-patch codes can't be used

[TwoTails]

With the way 1.6.4/1.6.2 forge works, you can't install mods in to the forge version.jar or, in technic's case, the modpack.jar without this code:

-Dfml.ignoreInvalidMinecraftCertificates=true

-Dfml.ignorePatchDiscrepancies=true

and because of this, some mods can't be used with the technic launcher as some can only be installed into the jar.

so, anyone got a fix for this?
