SVG export reverses/flips the text

[zeehio]

When exporting as SVG, the text is flipped and or rotated when it should not be.
Tested on Linux, Fritzing-0.9.2b.
I can't test on git master due to build errors (related to wrong libboost first, and libgit2 issues later).

Here is a simple example that can be used for testing:

SVG export (incorrect):

This has been converted later on to png with the GIMP so it can be viewed here:

PNG export (correct):

SVG figure to see the generated "svg code"

SVG figure (In a zip file, so it can be attached in a github issue)
bug_export_label_rotated_schem.svg.zip

Fritzing test

FZZ file (with zip extension added, so it can be attached in a github issue):
bug_export_label_rotated.fzz.zip

Additionally, the colors are not converted to the black silkscreen and "#F7BD13" standard copper colors. This makes some parts appear with white silkscreen, hard to distinguish if there is a white background (e.g https://github.com/fritzing/fritzing-parts/blob/master/svg/core/pcb/connector_power_pj202ah.svg)

Easy to reproduce with current 0.9.5 develop (and probably all other versions)
