Add support for "build hooks (since IDE 1.6.5)"

[jantje]

The arduino hardware specification https://github.com/arduino/Arduino/wiki/Arduino-IDE-1.5-3rd-party-Hardware-specification specifies Pre and post build hooks (since IDE 1.6.5)
recipe.hooks.sketch.prebuild.NUMBER.pattern (called before sketch compilation) is used by nucleo making the build fail

[jantje]

Workaround:
Use the latest nightly and add ${A.RECIPE.HOOKS.PREBUILD.1.PATTERN} to the project properties->C/C++ build->settings->build steps->pre-build steps
post build steps can be added in the post-build steps on the same page.
If there are multiple steps you can add them with ; as separator

the issue comes form picking "v1.4 Compile from source" at project properties -> Arduino -> lwIP Variant. I've chanced it to "v2 low memory" and the error was gone.
(see picture below)

There are more boards/options that have this issue. Problem is that make is not meant to insert actions like this.
I really need a think/research about this one

If the workaround as proposed in #984 really works that may be a good solution for most of the arduino hooks:

recipe.hooks.sketch.prebuild.NUMBER.pattern (called before sketch compilation)
recipe.hooks.sketch.postbuild.NUMBER.pattern (called after sketch compilation)
recipe.hooks.libraries.prebuild.NUMBER.pattern (called before libraries compilation)
recipe.hooks.libraries.postbuild.NUMBER.pattern (called after libraries compilation)
recipe.hooks.core.prebuild.NUMBER.pattern (called before core compilation)
recipe.hooks.core.postbuild.NUMBER.pattern (called after core compilation)
recipe.hooks.linking.prelink.NUMBER.pattern (called before linking)
recipe.hooks.linking.postlink.NUMBER.pattern (called after linking)
recipe.hooks.objcopy.preobjcopy.NUMBER.pattern (called before objcopy recipes execution)
recipe.hooks.objcopy.postobjcopy.NUMBER.pattern (called after objcopy recipes execution)
recipe.hooks.savehex.presavehex.NUMBER.pattern (called before savehex recipe execution)
recipe.hooks.savehex.postsavehex.NUMBER.pattern (called after savehex recipe execution)

For following hooks I see no real solution with the #984 workaround:

recipe.hooks.sketch.prebuild.NUMBER.pattern (called before sketch compilation)
recipe.hooks.sketch.postbuild.NUMBER.pattern (called after sketch compilation)
recipe.hooks.libraries.prebuild.NUMBER.pattern (called before libraries compilation)
recipe.hooks.libraries.postbuild.NUMBER.pattern (called after libraries compilation)
recipe.hooks.core.prebuild.NUMBER.pattern (called before core compilation)
recipe.hooks.core.postbuild.NUMBER.pattern (called after core compilation)

But the following can be fixed with the pre build cdt options because sloeber.ino.cpp is the very first file compiled

recipe.hooks.sketch.prebuild.NUMBER.pattern (called before sketch compilation)

The problem with the libraries and core hooks is that it assumes a order of compilation of the source files. CDT and make (and thus Sloeber) do not do this.
