Doctrine-0.11.0-RC1 Import substitutes all 'S' character on tables for an '_'

Also some upper cases letters on tables are transformed to lower case.

ie: supose the following MySQL table:
PM_SEQ_BESCANVI

Wen running Doctrine::generateModelsFromDb translate this to:
PMeQ_BE_CANVI.php

class PMeQ_BE_CANVI extends BasePMeQ_BE_CANVI

Then its a little weird to deal with your own tables with those names Table PM_USUARIS_TIPUS is transformed to: PM_U_UARI_tIPU_.php

etc.
