Added BETA api for Tab Bar/Tabs widgets. (#261, #351) (merged this feature from the from Docking branch so it can be used earlier as as standalone feature)

Browse Source 
- Added BeginTabBar(), EndTabBar(), BeginTabItem(), EndTabItem(), SetTabItemClosed() API.
- Added ImGuiTabBarFlags flags for BeginTabBar().
- Added ImGuiTabItemFlags flags for BeginTabItem().
- Style: Added ImGuiCol_Tab, ImGuiCol_TabHovered, ImGuiCol_TabActive, ImGuiCol_TabUnfocused, ImGuiCol_TabUnfocusedActive colors.
- Demo: Added Layout->Tabs demo code.
- Demo: Added "Documents" example app showcasing possible use for tabs.

The addition of new configuration options in the Docking branch is pushing for a little reorganization of those names.
Other Changes:
- Added BETA api for Tab Bar/Tabs widgets: (#261, #351)
- Added BeginTabBar(), EndTabBar(), BeginTabItem(), EndTabItem(), SetTabItemClosed() API.
- Added ImGuiTabBarFlags flags for BeginTabBar().
- Added ImGuiTabItemFlags flags for BeginTabItem().

- Demo: Added Layout->Tabs demo code.
- Demo: Added "Documents" example app showcasing possible use for tabs.
This feature was merged from the Docking branch in order to allow the use of regular tabs in your code.
(It does not provide the docking/splitting/merging of windows available in the Docking branch)
- Added ImGuiWindowFlags_UnsavedDocument window flag to append '*' to title without altering
the ID, as a convenience to avoid using the ### operator.
- Resizing windows from edge is now enabled by default (io.ConfigWindowsResizeFromEdges=true). Note that

- tabs: re-ordering, close buttons, context menu, persistent order (#261, #351)
