Subject: [PATCH] Customized BUILD_DIR in install.bat (#3920)

This is a very simple change that allow people to build Telegram like AppVeyor does it, but not in C:\TBuild (often C is "System Reserved" and cannot be used). Instead you can build it anywhere (from the visual studio 2017 x86 command prompt) like this:

    >set BUILD_DIR=%CD%
    >git clone https://github.com/telegramdesktop/tdesktop.git
    >cd tdesktop
    >.\.appveyor\install.bat
    >msbuild Telegram\Telegram.sln /property:Configuration=Debug /p:Platform=Win32

Some notes:

- I replaced all C:\TBuild with %BUILD_DIR%, even if it is decided not to merge this, keep that.
- %BUILD_DIR%\Libraries\prepare.bat might fail to extract the 7z Qt libraries for some reason (even if 7z.exe is in PATH) this has not been fixed
