Cache SA-MP installers for patching

[markski1]

When a user decides to patch a version of the game, the program should perhaps save the installer in a folder instead of re-downloading an already used installer over and over each time a user patches it IMO.

(I.E. If I decide to patch 03DL, then 037, then 03DL again, I shouldn't have to download the installer for that again, it should be saved in the computer.)

This would make things a fair bit faster for people who constantly switches between versions like myself.

The used storage space would be virtually meaningless by today's standards - A user could patch every single version and the installer cache would probably not even reach 500Mb (And the most likely scenario is that users will just switch between two or three versions, which wouldn't bring the cache size any higher than 60mb)

This is one of many features planned for 2.x.
