This fixes two display issues in the project template selector. The
first captured HTML tags in the template title display and the second
prevented more than one line for showing (at least on GTK) in the
preview. This prevented disambiguation between the various templates.
(cherry picked from commit 24b032ce5bf31b1d3d8d7de185c828ffa6b44647)
Add a check to see if the folder selected by the user contains a
project template meta data folder and use that folder instead of
assuming that it is a folder containing sub-folders with project
templates. The normal behavior is preserved when no meta data
folder is detected.

- Fixes a race condition causing the wrong page to be selected in
`OnPageChange`
- Allows the validate path and browse button to refresh the
template page even when the path was not changed. This is needed
since on OSX the page needs to be active for the templates to be
rendered.
Also add PAD_SHAPE_<PADSHAPE> equiv to PAD_<PADSHAPE> and PAD_ATTRIB_PAD_<PADATTRIB> equiv to PAD_<PADATTRIB>
(<PADSHAPE> = ROUND, RECT... and <PADATTRIB> =SMD, CONN ... )
