Alpha 1.0.25: Edit phone number in Settings.

Also fix build for GCC.
Also add scripts for GitHub releases management.

Alpha 1.0.24: Fix build in Xcode.

Alpha 1.0.23: Fix changelog message.

Alpha 1.0.22: fix couple of crashes.

Alpha 1.0.21: Use custom refcount for MTP types.

It seems that heavy using std::shared_ptr and std::make_shared
like it was before completely kills the compilation time.

Also HistoryItem::_create now uses perfect forwarding.

Alpha 1.0.20: fix crash in old Windows versions.

A shell32 method SHCreateItemFromParsingName was used without
checking if it was successfully loaded from shell32.dll (Vista+).

Alpha 1.0.19: Add MSVC++ bug workaround.

Alpha 1.0.18: destroying auth keys on sign up.

Also some debugging tools for mtproto endpoints added.

Alpha 1.0.17: crash fix in file open.

ShellExecute() call reenters Qt event loop, so each time we
schedule a delayed action (like destroying FileLoader) and after
that we call ShellExecute (in psOpenFile) we destroy it inside
this call and can't use it after.

So now we perform ShellExecute calls only delayed (using task queue).

Alpha 1.0.16: fighting crashes.

An attempt to fix a crash in MTP::Instance destructor + additional
logging there to find out how this crash happens.
