Added variables for git, curl & wget executables.

This makes it easies to use Vundle with gVimPortable (PortableApps.com) and PortableGit.

This seems useful and fairly safe but still needs testing.

Can you give some more background information? What was the problem using vundle with gVimPortable?

[cameris]

Vundle uses plain git, curl and wget commands and therefore these have to be in the search path. When using ProtableGit this is clearly not the case.
Hence with this patch applied, I have the following in my vimrc.

let g:vundle#git_executable = expand($VIM.'\..\..\..\PortableGit\bin\git.exe')
let g:vundle#curl_executable = expand($VIM.'\..\..\..\PortableGit\mingw32\bin\curl.exe')

Just an update, I finally got around to merging these into a release branch but I need to resolve some conflicts regard #699 and #684 😄

[layus]

Should be fairly straightforward as this PR factorizes the calls to the git executables.
Do you need some help to merge this ?

[ryanoasis]

@layus Yeah you are correct it should be but once I saw the conflict I just stopped 😊 because I was just trying to get it all on the same branch quickly.

I just need to look at it again, I don't think I need help but of course if I do I will let you know! Thanks 👍

Finally got around to getting these into branch/release 0.10.3

Have only cursory tested :VundleInstall, :VundleUpdate, :VundleSearch, and viewed the vundle log.

Side note, not sure when it happened (seems to even happen on master) but during my testing :VundleUpdate is VERY SLOW... maybe it is just on my end?
