[lua plugin] fixed warning
Removed obsolete files
Prompt the user before executing a project and suggest to build it
Use the new API call PromptForYesNoDialogWithCheckbox() in all code segments that prompts the user with an annoying dialog
No real changes, I hope; just fixes for wx3.1 deprecation warnings

The slight exception is in Plugin/cl_treelistctrl.cpp:
 m_dottedPen = wxPen( _T("grey"), 0, wxPENSTYLE_SOLID );
The wxPENSTYLE_SOLID parameter was previously 0, which was invalid: the enum starts a 100
[lua plugin] added Workspace and Project classes for userdata lua bindings
Git: make the git dialog: "Push all local commits" an annoying dialog that can be dismissed with a checkbox
[lua plugin] refactoring
Merge branch 'master' of https://github.com/eranif/codelite.git into LUA_SCRIPT
[lua plugin] added a way to retrieve the files of a project
