On updating Modpack, Launcher doesn't delete old mods

[danielford167]

Just wanted to say to you guys that on the update released recently, The Launcher when it updates your mods in the mods folder, it doesnt delete the old copies of mods, and so the client won't start.

For example, there are two forestry versions in the mods folder: pre 4 and pre 6
Extra Biomes has 2 versions: 3.1.0 and 3.3.0
Thermal Expansion: 1.0.8 and 2.0.2
Nei in Core Mods also: 1.4.1 and 1.4.1.2

Simple fix, by deleting the old mod zips, but thought I would say about it

Besides the obvious fix for this problem, it might be a neat feature to include upon mod pack update the previous mod pack gets moved to an archive folder when the update is downloaded and a revert feature is added. This way if a problem occurs due to bug or what not the end user can simply revert to last configuration and move on. Upon the next update the contents of the archive are deleted and replaced. Rinse and repeat. On a side note, awesome job so far to the whole team, the effort you guys (gals) have put in is appreciated!
