input lowercase/uppercase sensitivity

[fsmoncadaa]

Some parts of the input are lowercase/uppercase sensitive, and I don't think they should be.

For instance, replacing ionizeSpecie="POSITRON" with ionizeSpecie="Positron" in the following input results in an error.

GEOMETRY
e-(F) DEF2-TZVPPD 0.0 0.0 0.0 addParticles=1 multiplicity=1
F dirac 0.0 0.0 0.0
E+ PSX-TZ 0.0 0.0 0.0
END GEOMETRY

TASKS
method = "UHF"
propagatorTheoryCorrection = 3
END TASKS

CONTROL
ptP3Method = "REN-P3"
!This line gives error
! ionizeSpecie = "Positron"
!This line works fine
ionizeSpecie = "POSITRON"
ionizeMO= 1
ptJustOneOrbital=.T.
END CONTROL

Everything should be converted to lowercase or uppercase when parsed.
